Your explanation is the best compared to 3 other higher-quality teachers I watched on 0-1 knapsack problems.
@@ay9523 his explanation with solving seems difficult came to Jenny Mam understand successfully
same
true
Yes , absolutely right 👍🏻▶️
true!
We want more videos on DAA .....well explained and you have make this topics easier for us.
Thank you
The second day researching on how to tabulate this problem and I've found the solution here. Well explained! 👏👏👏
i understand the concept but in the end i never get the intution behind these logic..its more or less mugging up the process like what we have to do next..don't know about the other but if there is another problem same or little bit different from this i need to again check up the solution. btw thanks mam for explaining the process
I am a seller who has a bag which can contain 10 kg weight so in order to maxmize my profite I am selecting those items in those ratio
Follow books for understanding the full proof and the formal algorithm.
She has explained well enough.not sure what you can't understand. For every cell it's a choice between picking that or not picking that and comparing the profits
@@scuba485 bro it was a year-old comment and explaining the intuition behind the pick and nonpick and how u arrive at it is what I want to know at that time... solving 10 questions on 2d dp anyone can get the process in their head, from a beginner pov arriving at logic is the toughest part and that is the thing I expect in the video that I didn't get that's why commented it.
Try watching from take u forward, he teaches coding along too
Awesome tutorial, very detailed explanation:
a slight correction in P and W at top of table...
P={2,3,4,1} and W={2,3,5,6}
the values at index 2 and 3 is swapped for both P and W...
correct bro
can you explain this?
Thanks... I was implementing here and the matrix was not the same... I was getting mad :)
she sait it should be ascending order by weights
she took w in ascending order
Thank you so much ma'am, This is the best explanation of 0-1 Knapsack problem on youtube. This video cleared all of my doubts, Keep posting these videos.
Coming here after watching 2-3 videos and no one does it better than Jenny mam. Rock on ma'am!
same bhai
Yes bro correct ek dam🥳
ma'am u just saved my day, tomorrow is my exam.
Same here 😂
Kottaya sappu
Wow Ma'am. You are best explaining these complex theories in so simpler manner with detailed explanation that gives us in-depth knowledge with complete understanding of the concepts.
I have watched several videos on this knapsack problem however I couldn't understand well until I watch your thoroughly explained video.
I don't know this happens with me or every one .... The same concept thought by other teachers on youtube is not understanding... But when ma'am teaching the concept it is perfectly understood 😂😂😂😂
Thank you ma'am😊
I feel the same....
Now that is called attention😂😂
Jenny mam is awesome
@@rehankarol7453 😂😂
Wahh betai tu toh moz kar diya
Line maar rahe ho...😂😜
After searching many videos I have find the simplest and easiest way 👍🏻
Thanks mam ✨
Brilliant lecture. You explained exactly in the same way how 0-1 Knapsack algorithm formulated. I am able to relate the complete formula. Helped me to avoid my phobia for DP.
i lost hope on the exam but this particular video boosted me like anything!!! thank you!!
This explanation can't be more precise and easy to understand this ma'am ! Kudos to you!
your explaination and tricks are just awesome, that is why people come to learn these lectures from youtube even though they learn from their Universities
imagine having ma'am jenny and sir. varun singla as teachers at the same university.....all students will be toppers :)
this is by far the best explanation to the knapsack problem ever! thank you for uploading
Superb
Simp, gate smashers>>
Just wow ...the best possible way u teach❤ ....I sometimes just think how good teacher u r and on the other side same age girl doing shit over tick tocks.😂
I am just trying to give my best. 😊
@@JennyslecturesCSIT that is why people like u the most.✌😊
😊
Right...
Good teachers need to be valued. Subscribed ✅
Glad that I chose this video to understand the concept, nicely explained👌
Thank you, I could recall the problem implementation with your explanation... Small correction if u can consider is..The formula given to fill the cells will not work for the cells in initial columns where that row's weight is less than that column's weight. Try applying the formula to the cells where we have 0s filled. In that cases, we can copy the values from above rows which ofcourse u have covered in explanation... Thank you...
Mam aap jaisa teacher mile to sabka padhai m mn lgega ..aap koi bhi concept ho ekdm ache se clear kr dete ho..thankuu mam
did u undrstnt the concpt if yes....can u tell me, is it necessary to sort the weight array?????
Your are the only one who make me pass my exams... I love your teaching. You are the best teacher from which i ever studied. I wish God will meet us anywhere so that i can say thank you to you for all the knowledge that you provided without asking for any money ♥️♥️
I have exam, so i was looking for a perfect video where someone explains 0/1 knapscak. And i finally found it. Thank you so much, you helped me a lot!
As a seller who has only 8kg bag at shop
This video is very helpful ☺️👍
Cleared my doubts on 0/1 knapsack. Thank you so much
The explanation is good, You do actually solve the problem completely.
Correction: We don't need to sort the weight array.
public void ZeroOrOneSolution(int profit[], int weights[], int sackCapacity){
int K[][] = new int[profit.length+1][sackCapacity+1];
for(int i=0; i
Its just amazing. So much love and respect from Bangladesh
आपका बहुत बहुत धन्यावाद 🙏
आपकी मदत से ही हम ये सीख पाए👍
आपने बहुत ही अच्छे तरीके से बाते रखकर समझाया हे इसीलिए आपका फिरसे धन्यवाद 🙏

i was watching the knapsack 0/1 problem on the other different tutorial for last 1.30 hours but i can't understood, when I saw this video i understood easily each step. thank you so much ma'am . 😍😍
You explained it in a very clear way than my professor. Thank you very much😊
27:14
there is an mistake it's (1 0 1 0 ).
you can cross verify if we are considering the object ( 1 0 0 1 ) its exeeds the knapsack capacity.
True I was thinking the same
Yes u r right bro
Actually 3rd and 4th value was swapped
You are just awesome mam
Wish i could have the authority to my college i would have battled with my teachers to bring you in as our algorithm teacher
Rock solid teaching technique
God bless you MAM
tons of love from me to your hardwork
Thank you so so so so so much !!!!!
what are you doing currently?
I'm a Mechanical Engineer and I know the basics of C. Though I'm a Mechanical engineer your videos are easy to understand and awesome. Thank you mam!
I have watched many videos about knapsack problem, and now I declare that this is the best of them. Thank you very much for sharing 👏
can confirm.
Jenny mam ,Iam learning alot in DS and DAA from your lectures.
Thanks alot to you for your great work on providing best way.
I found 0/1 knapsack problem please look that we would have xi={1, 0,1,0} you have written there xi={1,0,0,1} .
She checked the set given in the question
This is what for i was exploring comments thanks man
Yes u r correct bro
This is the best explanation of 0/1 knapsack problem on the internet.
You are the best mam, thank you for working so hard for us.
After watching so many videos , she explained it very well.
Honestly, I had seen a lot of video of knapsack problem (0/1) .But this video explains my every doubt . I don't want to take your more time to read this comment
Overall you explained very well !!!

Jenny comes out on top for this one. Strangely, this is the best explained/understood video on this topic.
Very Useful for people who are appearing for Interviews.
Thank you very much madam I always had a lot of doubts and afraid of doing knapsack problems now I am very happy and able to solve many problems on this model.
best explanation of 0/1 knapsack problem in youtube
Thanks a lot for sharing your views in such wonderful words 😊😊
Understanding slowly but it's clearly understood 😇👌
Those eyes ,,,,make sure I can concentrate on the topics goodly....you are such a fantabulous teacher😊🤗
wow finally after many lectures of others here i understand everything
6:33
No, it doesn't need to be in ascending order!!!!!
*I think* it should be in increasing order since we are giving priority of each objects so it's better to write that way.
@@abdullahalmasum5542 No, the algorithm works whether it is sorted or not. Sorting the linked value is not easy to program.
@@Sourav9063 you are correct,bro. I made a mistake but learn something good. thnx😊
The answer is here also:
stackoverflow.com/questions/29853579/do-you-need-to-sort-inputs-for-dynamic-programming-knapsack
@@abdullahalmasum5542 Just a suggestion. If you understand the algorithm instead of remembering the steps or formula, it will be easy to get why the order is not important :) . Most of the online lectures I found don't do this.
saw 2 other TH-cam videos and yours is the easiest and best.
Thankyou so much mam ,the way u explain every point bit by bit in detail is simply brilliant.
TH-cam to Me :- Wake Up Early In The Morning And Do On Thing Learn Something From This Teacher #HighlyRecommended ♥️
Me To TH-cam :- Yes Sir..🌹
Mam I am your big fan. After watching your lectures .thank you so much mam.what a explanation.amazing mam🙏
Madam you are wonderful your teaching is awesome
only u have made me explained mam. great respect ... everyone is talking shit. Either they are making memoization tabel or they are explaining code.
Thank you SO much dear mam.. Your explanation is too good.. 🙂
I watched other videos to understand this problem but couldn't, but you explained so well ,, thank you ...🙂
Very well explained. I understood the concept fully and clearly.
Didi this is the best video on knapsack problem. Keep posting more videos didi.
overall your videos are very nice and your way of teaching is amazing , you are my best teacher
Waah bete wah
Wah bete moz kardi...
Tum to bade heavy driver ho
toughest problem solved in the simplest way!! Thanks mam.
Mam , Your voice is sooooooo, sweet .. I want to learn forever . Every time a new thing .
Hope you can publish more video! So helpful and best video!
Deep knowledge makes humans incredible 🙂
Ma'am the method that we have been provided in our university book that we usually refer is so long , whereas yours method is simple and short which I would like to prefer it , but my question. is ,Will I get full marks by referring your method in exam?😅😅
Placement hogya?🤔
You're a lifesaver Jenny.
Thank you Mam.....Your explanation is full deeply and your teaching way mind blowing....thanks love you mam
thank you so much, I watched a lot of videos about this problem, but this is the best !!!
Hands down Jenny is the best CS teacher on TH-cam, watched many videos but only your explaination is going in my head!
Amazingly explained. This is so good. All The Best.
I am really very happy i got to understand much better.Thank you so much for sharing such an amzing content.
Very nicely explained.
Although I don’t think the sorting of the items according to the ascending order of their weights is necessary.
thanks Mam assignment solve hu gai. I don't know where u from India or Pakistan but respect from humanity.
Watching this 30 min before the exam 😅
I was not getting the formula how it came. But, now it's so easy. Thank you Mam. You are beautiful.
You are teaching very clearly thank you so much
thanks for dropping such helpful videos, ma'am.
Amazing explanation mam...👌
osom...i have watched few video of u N i believe they r one of the best currently on youtube ..plz upload more video on ur channel...
your way of teaching is awesome ma'am😄😄
Such an amazing video explaining the topic. Thank you so much. Watching it one night before my exam. Very helpful..
Mam ur explanation is very clear. It's now easy for me to attend this type of problem. Thank you for teaching mam🙏🙏🙏🥰
I'm ur student from Puducherry mam
mam is this the best example to learn 0/1 knapsack problem
you teach in an easy way
Thank you very much. Simple,short ,concise ....
your teaching style is the best one...,and u r so quite
Thank you so much mam...to explain this topic so much easyly
thnx mam bahut achhe se smjh aaya concept
Hi Jenny, Thanks for videos on Dynamic programming. you are doing a great job.
I have one question
from where we got this formula ? How it was derived?
😂
Good explanation but logic seems to be slightly wrong. For example, (2, 8) value should be 6 as we can have 2*4 -> 2*3= 6. Why 5? Seems like taking value from above row and adding seems to be wrong, you need to take it from same row. Also, adding 0th row and column is not much useful. Thanks for sharing your knowledge!
ma'am i think no need to sort w[ ] array
