Time Complexity is Rate at which the time taken increases with respect to input size. Time Complexity is calculated in BigO notation. 3 rules for calculating TC: Calculate with worst case scenario. Avoid Constants Avoid Lower Values BigO-worst scenario Theta-average case scenario Omega- Best Case Scenario Space Complexity: SC is also calculated in BigO notation itself There are two spaces. 1.Auxilalry Space:The space taken to solve problem and store solution. 2.Input Space:The space taken to store the inputs. C=a+b Where C is auxillary Space. a and b are input space. While coding, tampering the input for SC is wrong practice.
Understood. Today is November 18th, 2024, i have started my journey with Strivers SDE sheet, i will come here periodically to update my status and my offers! Wish me luck!
Every time, when i started studying about DSA, i felt bored or frustrated, but this time by watch your video lecture, i didn't feel that way, instead i felt motivated to continue on this course, Thanks man i really grateful to you
Today I am getting started with the playlist. I have 12+ exp already and now learning DSA to enter into my dream company. I regret the wasted years but I hope I am not too old to start now. All the best to everyone❤
Bro Can I learn this DSA for solving problems and improve critical thinking not for interview purpose Ofcourse I'll face that rather than that is this good ???
understood. i have tried different platfdorms to learn DSA but you are the only one i am continuing and getting concepts crystal clear... Thank You Striver!
He most probably made this video some days or weeks ago .... and his editor or he might just put it out today.. Ofcourse he's not gonna waste 31st like this 🤣
@@souvikghosh5768 bro I'm talking about students who are watching videos right now or first January 🙂 I know very well video can be scheduled as well in youtube when it will be released 🙂 Happy new year bro 💫
Today is 25 July, 2024 and I am starting Striver's A-Z DSA playlist. Will comeback here periodically to update my progress and let you all know about the offers that I get. Wishing you all lots of luck!
@@bibek31566 oh, that's great to hear! I'm doing well and staying consistent. I wish you the same for your future endeavors!. When Delving deeper into a subject often reveals interesting details.
I am a final year student literally i tried underdstanding time and space complexity since 3 years refering all top youtube channels but did'nt got this much of explaination as i got here , tq so much for your explaination sir , we are blessed to have you , i hope i will cover all your videos . Tq so much sir once again
Today is November 16th, 2024, i have started my journey towards DSA using Strivers SDE sheet, i will come here periodically to update my status and my offers! Wish me luck!
"Wow, I finally understand the concept of Time Complexity! Your explanation was clear and concise, making it so much easier to grasp. You're a superb teacher, and I really appreciate your ability to break down complex things and make them understandable. Thank you for sharing your knowledge and helping me expand my understanding. Keep up the excellent work!"
Hey did u checked the take u frwd website and A-Z sheet there ? I'm confused that in that sheet , there is search query auto complete prblm is there in practise for input/output topic....how can this difficult prblm could place under this simple io topic..did u solved ?
Today is 6 Aug 2024 ,I have started this Striver's A2Z DSA Course .Wish good luck to all who have started this journey and hope you all accomplish your dreams. 😊
Thank you, Raj, for explaining the concepts in detail. Although the topic was not naive to me listening to it still gave me info that I was not aware of. I am liking the way you are explaining the concepts and helping the community to understand DSA properly.
This has to be the best explanation for time complexity on TH-cam. I couldn't understand what my lecturer explained and other youtubers also but your explanation i understood in the first explanation itself. Thank you so much for this brilliant content.
STRIVER I recently completed your DP series it's amazing and i understand well and good .. But in this video you look so handsome as your explanation.. Happy new year keep glowing and make everyone glow with your content......
This is the first time I've come across your video. You are a blessing for mankind. All my years of doing computer science engineering I've never understood concepts like how I understand right now. Thank You so much for your videos. I'll be watching all of them one by one. You are such a LEGEND 🫡 Thank You ♾️
happy new year to you too bhaiya.....just one request please keep uploading videos for a2z dsa course MORE Frequently because if break is too long between videos then it affects consistency and we end up leaving course in mid way so hope we will see videos more frequently from now !
Started this video playlist just like every other tutorial video to be left in middle . But brother the way you explain is just too good . Will make me stick till the end. Thank you for the efforts. 💪
awesome 🔥 just a suggestion. keep the facecam video pinned in right/left bottom corner and the screen behind that on entire screen. that way, the video will look a lot more neat and engaging also. Thanks
We don’t wanna stretch the ipad screen reso too much unnecessarily. We will have it like this only. It has worked well for us in dp, graphs. Post experimenting, we have found this to be more engaging and to have more screen presence
finally in the right place to learn everything, i'm not feeling boring at all because of the problems, which makes me so curious to solve and Teaching level, is like even a school student can understand it so explained it so easily.❤
After being inconsistent with DSA for a while, I am finally starting Strivers A2Z DSA Sheet on 10 July 2024. Will comeback here every 10th day of the month to update my progress. All the best everyone!
Today is 24 august and I am starting my dsa journey today.I am currently studying final year.I have just 6 months to learn dsa completely.please all of you wish me for best.And suggest me to get placed in a good company 😊
10:43 actually in this question no.of operations will be 3n+2 as initializing i with 1 is also an operation and at the very last when i = n+1 we are checking the condition again and not printing anything and loop stop. so checking the condition at very last is also an operation. thank u.
I'm starting my preparation today(11/07/2024). I have started so many times, but i have failed to maintain the consistency. At least if i add the comment here may be it'll remind or push to maintain the consistency. I'll come on every month on same day and update my progress.
Average time Complexity isn't necessarily an average of best case and worst case , this is valid for some specific condition.Average time complexity is ratio of summation of time taken by all inputs possible and number of different inputs .
Let's march ahead, and create an unmatchable DSA course! ❤️
Happy new year everyone, wish you loads of success in your life :)
thank you sir giving everyone this magnetic course ,solute to you 🥰🥰
happy new year and thanks for this amazing content.

Where can I get 0:06 that DSA Sheet of Striver's ? Link ? Or site's name ?
Bro i have never seen a guy explaining this much well . Your way of teaching is very rare
pepcoding is also a gud channel, NOT FIGHTING, just leeting u know about one more GEM.
@@aayush4056 ohhhh thankyouuu , I'll surely check it out
I started this DSA sheet on 06-08-2024 and its very helpfull for me to learn in structured way .thank you
Me also❤
how is your dsa learning journey is it going well?
Time Complexity is Rate at which the time taken increases with respect to input size.
Time Complexity is calculated in BigO notation.
3 rules for calculating TC:
Calculate with worst case scenario.
Avoid Constants
Avoid Lower Values
BigO-worst scenario
Theta-average case scenario
Omega- Best Case Scenario
Space Complexity:
SC is also calculated in BigO notation itself
There are two spaces.
1.Auxilalry Space:The space taken to solve problem and store solution.
2.Input Space:The space taken to store the inputs.
C=a+b
Where C is auxillary Space.
a and b are input space.
While coding, tampering the input for SC is wrong practice.
input space is space taken to store the input

Thank you, Raj, for explaining the concepts in detail. Although the topic was not naive to me listening to it still gave me info that I was not aware of. I am liking the way you are explaining the concepts and helping the community to understand DSA properly.
Can I learn this for not interview but for the solving and coding problems???
Please respond 🙏
This has to be the best explanation for time complexity on TH-cam. I couldn't understand what my lecturer explained and other youtubers also but your explanation i understood in the first explanation itself. Thank you so much for this brilliant content.
same
Understood!! Already Knew this topic but learn some extra points especially about how to represent in interviews..
STRIVER I recently completed your DP series it's amazing and i understand well and good ..
But in this video you look so handsome as your explanation..

.But infront of you all are wasted.
Hey, is strivers better than gfg? Because even I purchased the gfg course..
This is the first time I've come across your video. You are a blessing for mankind. All my years of doing computer science engineering I've never understood concepts like how I understand right now.

happy new year to you too bhaiya.....just one request please keep uploading videos for a2z dsa course MORE Frequently because if break is too long between videos then it affects consistency and we end up leaving course in mid way so hope we will see videos more frequently from now !
Started this video playlist just like every other tutorial video to be left in middle . But brother the way you explain is just too good . Will make me stick till the end. Thank you for the efforts.

awesome 🔥
just a suggestion. keep the facecam video pinned in right/left bottom corner and the screen behind that on entire screen. that way, the video will look a lot more neat and engaging also. Thanks

Today is 4 sept. and i am starting DSA from this playlist..hoping for the best
The end of Pattern...Amazing journey...👍
I have started this A2Z series from 25th July .. understood 🥳
First lecture complete. Understood Thank you Raj :D
Today is 8 sept and I started my DSA journey.❤
Really your teaching is awesome, helping me a lot in understanding the concept
great learning experience everything he taught is very clear and easy to understand
Understood Sir!
Thank you Sir!
You are doing a great job Sir!
What a clear explanation striver .. keep it you and grow forever
This man is doing god's work by teaching us
Hope you achieve even greater heights
thankyou for helping so many students striver!!

I like your way of explaining and it's amazing.
Thank you for this video.

raj bhia this is amazingly explained i was so confused for how to calculate thank you!
I have started DSA course on 30 Sept 2024. I will keep weekly updating my progress.
So what's the update bro?
Today i'm starting this playlist , will update if i get any new job (14/10)
please like and comment so that that i don't miss any day.
Thanks

Today is 24 august and I am starting my dsa journey today.I am currently studying final year.I have just 6 months to learn dsa completely.please all of you wish me for best.And suggest me to get placed in a good company 😊
That was a great Explanation for Time and Space Complexity
Thankyou brother for this wonderful teaching
very nice explanation by @takeUforward
in 22:49 the time complexity is actually O(N*W) as the inner loop is also a for loop the number of steps are N*W
lets go will complete these playlist along with sem 1
Thank you bhaiya for such amezing lectures understand everything ❤ I think if I follow the course till the end I'll be very good in DSA🙂↔️🙂↔️🙂↔️
10:43 actually in this question no.of operations will be 3n+2 as initializing i with 1 is also an operation and at the very last when i = n+1 we are checking the condition again and not printing anything and loop stop. so checking the condition at very last is also an operation. thank u.
Found this gem at early stage, Thank you Bhaiya
Understood bhaiyaaa.....great teaching
1st sem is about to start in 2 weeks, started DSA on 29th Aug 2024
Understood♥
chill maar bhai abhi, 2nd year se start karo DSA
abhi web dev pe dhyaan de
Thanks a lot Raj Bhaiya. Understood everything and doing good.
you are the best brother😍😍
I already learnt time complexity from a lot of videos but this video somewhere hits different
iam jacksparrow. today the date is 17 july . i am startingf this dsa course.i will complete in another 3 months.
Bro there are approx 300 videos are you sure that you are about to do this in 3 months?
I am starting this dsa course today and will come back when i compete it
Today Nov 23 2024 I am starting the striver's A-Z dsa course. I am updating the process after I got a job
understood bhai, thanks for amazing tutorial❤❤❤

directly to the brain sir ,understood sir ❤❤
