Thanks for having me on the channel!
Advice to viewers: Use this video to understand how to express your ideas, how to clarify the corner cases and confusions, how to communicate with the interviewer etc.
It doesn't matter even if you say something wrong or get stuck for a bit, as long as your explanation and thought process is crystal clear.
Best of luck guys!
I am sure your advice and this video will help many ❤️❤️
@utkarsh what should be the rating of this problem on Codeforces?
Also thanks alot for refreshing my Bitmask DP concepts :p.
Thanks for putting out really valuable resource!!!
@@anktrj around 1900 i think maybe 2000, idk
@@utkarshgupta9858 got my answer, thanks

Most important part , make the interviewer believe you have not solved this question before, even if you ate up half the codeforces and leetcode.
😂
Haha 😂😂
jor jor se bolke scheme btade 😂
Lmfao "ate up" 🤣
😂😂
🙂utkarsh didn't solve this hard question within an hour , as he told it took him 3 years to reach this position where he can solve these kind of questions within an hour , this was really inspiring , thanks for the amazing content 😃
Haha correct. But I would like to point out that I'd have done it in 10~15 minutes if I didn't have to explain it and write the code on google doc which doesn't even have indentation 😂
@@utkarshgupta9858 For ur level this question is easy-medium categories. Btw big fan of ur problem solving skills
@@utkarshgupta9858 helooooooooooo
@@rishabhchoubey3569For him it's easy an Expert in Code forces can also solve this i think
Mazak mazak mei hi nahi bana jata India ka top coder, there are hell lot of frustrating moments behind the scenes !
Kudos to Utkarsh 🥂🥂
And keep coming with more such mock interviews 🔥
sach pravachan !
True Rohit! There’s a long journey behind this one Interview ❤️
I am watching this video from 1 hour , I really loved it , ek ghanta kab nikal gaye pta hi nhi chala , Thanks Keerti & Utkarsh , It's really nice to watch him doing complex stuff in a simpler way .
Hope you like other videos as well Madhur. Thank you! Means a lot 😇😇
Really amazing!
Didn't understood anything but liked the way he explained.
🤣same here
Same 💀😂
Same 😂😂😂😂
Understand*
Look at him, so inspirational. Really impressed how you thought of the solution with continuous talking.
Dude is so comfortable doing this. I would start to shiver at the sight of such a problem.
Awesome work Utkarsh
I would also be extremely scared 😂
@@KeertiPurswani helooo
Gghjkk
wtf man !! this video i mean watching this interview its like depression(not like in bad way its like motivation now have to do more ) man like so much talent and so much to learn ...thnks to both n i think i have to study more ...
We always have to study more😅😅 But hoping the video is a good motivation ❤️
Red coder in red hood in the house🥳 Amazing mock interview!!
You are very humble and polite.Watching your videos helps me to be positive and believe in myself and to continue strengthen my coding skills.Keep making videos,we love it.
Thank you so much Prathamesh. Means a lot to me❤️❤️😇🤦🏻♀️
Please make hard mock interviews more...because people like me couldn't understand the solutions of hard problem even by reading, and this guy really made me understand a hard problem....
41:58 utkarsh be like, let's just test sample case and submit it. Dry run? feels weird 😂😂
Thanks @Keerthi for conducting this mock tests it cleared many doubts for me☺️
So happy to know. Hope you like other videos and interviews as well ❤️😇
Please provide 4-5good resume templates for freshers to apply at tech giant's.its need of so many people

Proud that utkarsh bhaiya is from my college. Me along with many others at iit bhu, are heavily inspired by him ❤❤
Best I could come up with is the brute force solution... The part where he reversed and derived the DP solution is absolute genius.
We learn with time and practise 💪💪
Lol it was like a Uno reversal card
This problem is a classic problem of dp with bitmasking similar to assignment problem or travelling salesman. This guy's a red coder, so he obviously would have gotten it at the very site of it, but the way he explained and solved it made all of us and also the interviewer believe that he arrived to the solution at that very moment. Kudos to that. 🎉
He is a prodigy from my college !
Kudos man 🙌
hes an iitian lol
Can you please upload what happened before this part of video, where he solved the questions very quickly.
The question may be hard, but it's also a very standard bitmasking question. If someone has ever practised bitmasking, they are very likely to have solved this before.
Would've been cool to see how Utkarsh handles not only a hard question, but a question he hasn't seen before, in an interview.
true..and hearing them talk about its difficulty in the end has shot my confidence to the roof..until tomorrow when a leetcode medium will humble me back
Keep coming up with these , these mocks are so much helpful....
Also great job Utkarsh 👍❤️
many thanks for having this great mock... this is helpful in guiding on how to proceed with such problems.
Great video and nice explanation but I would classify this problem as a Medium-Hard level instead of Hard level for competitive programming. But yes, for interview purpose this is considered hard.
Thanks for making this type of videos on youtube and that's why we can know how ask problem in coding like stuff.......
It's helping us a lot...
Thanks you so much ❤️❤️
Correct me if I misunderstood the question. Total number of unique caps are 100. Each person having a collection of these 100 caps. Total number of arrangement will be
100*99*98*97*....*(100-n).
lol funniest thing I read today
Please also bring jeel vaishnav on your channel. He has qualified google hash code world finals and currently a USC student and a codeforces grandmaster
2^n = 1
I was just thinking that its not possible to store information for 100 caps, and that very moment he reversed the question and I understood what he is up to.
He was so blushing when keerti asked if he wants to say something about Interviewer....
Some mistake/typo
if(possible[100][(1
I just wanted to know if my approach would also work for this problem. I will count total number of arrangement which will be the product of number of caps owned by each people and then subtract duplicates from the total. The main challenge here is to count total duplicates. For each cap id (1 to 100) I would go through each people and find how many duplicates are there and knowing cap counts for every other people, I would know how many duplicates can be formed.
i dont think so this is hard for utkarsh who do more harder problem than this on codeforces
The number are not flexible they are fix in this setting
create objects like
selection(string p, int i)
string person[p]
int cap [i]
raw_input(p)
i = 100
and then populate both arrays through loop
then assign with random and match function to if matches random loops again till all 10 person are assigned a cap finishes the loop, then displays the result of assigned cap along with persons name with print()
During contest Utkarsh finishes this type of question in 5 to 10 minutes.
Problem very similar to travelling salesman problem and he is grandmaster it would be kpop for him 😂 but the way he came up with soln and just code it with no problems .. i mean thats incredible
I am on a bench in a company for almost 1.5 years. So zero real experience. I tried doing some small MERN projects but those projects are very easy. But these small projects are the only things which I am able to put in my resume. So how can I handle my experience situation with the interviewer?? Should I be honest or should I try to talk my way out of it. It would really help if I can get your opinion on this. Thanks and sorry because I might copy this comment in your other videos comments so that you can notice this sooner :'(
Can you do a mock interview with errictoh...it will be so exciting...
we also want a video on mock interview with striver 🔥
I think U should have given the Interview because he is a google level code + India's no.1, so obviously he will win
dude its just a mock interview...no one is trying to win anything here
The interviewer is so beautiful, I would have forget the code🤣🤣😍
3 years into devlopment
I hate those time complexity questions
My point is u have alorithms in Internet
Then y u need to spend time in learning them
Learning framework
Web frameworks or mobile development
Devops
Really I don't understand why PPL go after time complexity and algorithms
Bt u guys are really great, doing things that I can't imagine to do.
After watching this video I'm scared to hit that subscribe.
Bt I wanna follow u
U gave me inspiration today to lean towards DS and algorithms
Frameworks may change day by day , bt problem solving will not be changed
But frameworks can only do the frontend thing who will optimize the computations in the backend. Algorithms can be found on the internet but first you have to know where to use which combination of algorithms that can optimize the computations needed.
Can someone explain to me why this isnt just combinatorics? For example 10 people 20 hats the first person has 20 options the second person has 19 choices the 3rd has 18 so 20×19×18×17...
Man!!! I just learn so many things from this single mock interview, I will definitely put this video in favorite list.
the interviewer is kind of not involved in the process
@@avetiqasatryan1540 true
You all expect all interviewers to be involved?
@@KeertiPurswani not everything as such but i saw many interviews where the interviewers ask again and again if we are missing on anything in question and clear that out. As i appeared all faang interviews. We should also ask everything before starting any solution. but in case we miss.
But yes i someone is highest rated in codeforces then probably not
@Keerti I want babbar bhaiya mock interview whoever wants this please like this comment
orz sir 🤩🤩
i had a confusion.......instead of keeping a "possible" matrix can we not have the dp matrix all initialised with -1 ?!
That on video tips are just amazing 🔥🔥
Thanks ❤️❤️😇😇
Utkarsh be like .
What the hell , N is just only 10.
It's simple DP with bitmask
I guess permutations and combinations can help here ?
Hi kreeti Didi , I am a software developer in Cognizant and preparing for Fang Company. I am passionate about teaching DSA and Algorithms and web development. Can you give me change to teach on your tube channel, So that It will become bigger Community.
Leetcode Q : Number of ways to wear different hats to each other
Where can I get this question to practice? Please provide some link to leetcode, gfg, interviewbit or codeforces or others (for practice and trying out different approaches).
i am in class 11 and a chapter named permutation and combination can solve this question
n people with 100 caps
of 1st person has 100 option to wear
the 2nd would have 100-1 option
of to wear unique caps then
n th person will have 90 option if n=10
other wise 10 cases will be formed
ranging n form 1 to 10
with n=1 person having 100 options
correct i agree.. ans should be 100*99*..91
if all person have each (1 to 100) caps in their collection then why my answer is not 100* 99* 98*.........upto*(100-n+1). because select n caps out of 100 (100 c N) ways and arrange these caps for all n person( n!). so final answer is (100 c N)*n! which is {100* 99* 98*.........upto*(100-n+1)}.
Ab aayega na majaaa
it was really a hard problem , i got the approach but coding it is really really hard
bro solved my doubt on bitmasks in the middle of an interview 💀
what is that doubt?
@@allaboinadivakar1976 I did not understand what the "mask" in bitmask was.
Thank you so much. It blows up my mind
There is a easy way to it i suppose "n choose k" for the permutations .
how does n being equal to zero prove to be of any use?
Keerti stack just overflowed 😳😳
He is a real sigma
This is all because of tremendous practice only!!!!
Agreed!! 😇😇
Let's gooo!!
I am trying to understand but not understood anything :(
This problem is easy for CPers but its is nice watching you are holding it even though you don’t know some CP tricks…
@2:58 n can not be > 100 if we use pigeon hole we can notice if n > 100 no such arrangement is possible.
utkarsh guptha = legand's swag.
Codechef pe same problem "Little Elephant and Tshirts" ke naam se hai , wo maine nhi kiya hota to ,It would have been very difficult for me to comprehend this question.
he already spend 2min on reading the problem, so how they are solving whole the contests questions in 10min?
Sab coding hi kr rhe hain..iss hisab se future me bas software developers hi honge 😂😂
mujhe toh solution dekhke bhi samajh nai aaya :")
It wasn't that hard to crack. Even Expert rated coder can crack this standard problem. But yes for interviews it was indeed hard.
Hi Nikhil , the videos on my channel for majorly for interview prep.
1. CP experts might be able to do quest but the video also shows how to express yourself in interview, his structured approach and a few pointers from my end as well.
2. There are many who aren’t CP experts and prepare for interviews. For people like us, this is definitely hard level.
Copied the LinedIn reply since you copied half comment🤷🏻♀️
@@KeertiPurswani no need to get offended though on LinkedIn comment, sharing approach isn't bad when someone can get hint from it instead of watching 1hr video to get the crux.
Nevermind :)
@@NikhilKumar-of5gb hater energy 😄
Fact is he impressed the interviewr
I could've written the recursive dp. Iterative dp formulation was very good.
Im not able to focus because of you whole 1 hour im trying to concentrate but I didn’t control and just watched you for 1hr 😊❤
no wonder why he cracked google and is the top coder in india
Question are really interesting I watch complete vedio and really amazing 🤟👏👏
Thanks Dheeraj. Means a lot! Hope you like other videos as well! 😇😇
Madam i am in third year i am inteovert and i am getting too much presuure which i am not able to handle now getting panick attacks i am suffering a lot didi any suggestion please
Please do mock interview with striver from takeuforward youtube channel, and give him the hardest problem(Brahmastra) you have.
100*99*98*97……(100-n+1)
Is this correct answer? Please reply
13:20 he is trying to right step but he has somewhat typing 'stepm'- stepmom 🌚
Only legends get it 😂
He is real-life god ❤️ excellent video
Question is vauge. I don't undestand why is this considered question hard. This is a simple combinatorics question. No wonder we will get bad lot of programmes in future. I can't expect an int to float evil bit hack followed by newton rahpson iterations to get inverse square root quickly from someone who calls this problem hard. You could have at least added a constrain where ith person is not wearing ith cap to make it a little more interesting. Please change thet title of the video, don't lower the bar by calling it hard.
I havent went thru all comments...but its a very basic question of permutation and combination.
its like how many ways can you choose n =10 numbers out of 100 without repitition ?
I wonder why ppl do lack this mathematical mind.
Is it valid to wear a cap in an interview?
Haha, he had asked me before interview if it’s fine. I was chill with it ✌️
Yes for red coder, red cap is fine😂😂
@@KeertiPurswani May be for cold environment.
@@AlokTripathi Ya
Mam can you please paste the question link as well. Will be very helpful
PIE also works right. I guess it's equivalent to the DP
when are you going to do interview with tourist😀
orzzz bhaiya :) _/\_
Will come back here in future!
From next time please include the sample input and output as a part of question.
It’s a mock interview and not all interviewers will give sample input and output. Trying to keep it as realistic as I can😅
@@KeertiPurswani ok thanks for the reply😬😁
I don't find her interviewing skills to be optimal to be honest! I feel you are not connected to the person at all. Hope you take this feedback in a constructive manner. :)
Jabardast, pata chal gya, India no. 1 kya hota hai.
ORZ🙌🏻
Ma'am
For any coding ninjas courses
Will there be life time access of all courses from coding ninjas
Like udemy?
No
The simple way to look at this problem is selection of n different caps out of 100 caps. The solution is 100*99*...(100 - (n-1)). Think in permutations & combinations, like nCr
The "Hi Guys" is trademark.
Can someone please tell me whether nCr~~~ (100Cn) where n= number of people will be the answer of first question or not?
the outro/music is too flashy & feels harsh, something soothing would be better I think 😅
