Leetcode - 322 coin change had first column with zeros But this one is being filled with ones Can you explain ? Better to have consistent base case for all knapsack type problems

I have gone through many solutions for this question explained by others, But, Your explanation is way more acceptable and understandable for even basic concepts used in between of solution Thanks a lot for this explanation Have a good luck !

Amazing Dude
Comment from : manoj jain

This is a hard problembrIf someone did not work on this problem before, and if they automatically derived this formula in 30 minutes of interview by themselves, they are god levelbrReally dont understand why interviewers ask such questions in interviews and expect this to be solved in optimal time complexity in 30 minutes
Comment from : Data Man

This was a very well thought out and explained approach to solving dp problems!brbrOther channels quickly go over the 2D array but don't explain how it's made I still need more practice to do this on my own 100, but thanks!

thank u

Good work 💯

What will be the time complexity of 1D solution
Comment from : Shivam Baghel

thank you so much sirbrI am not going to write a comment more than this because if i started to write comment on your explanation its not going to endbrthank you sir once again from bottom of my hart❤❤

I am following some courses for DSA but for a clear understanding, I repeatedly have to come back here You have something😁
Comment from : Nitesh Singh

Amazing Making DSA easy
Comment from : Shubham Agarwal

I can see how subset sum count, and coin change 2 is related basically it comes down to inclusion and exclusion After watching 10 videos on dp, i have gained confidence in solving dp problems Thanks techdose ^_^

Linear DP solution with meaningful comments O(n) Spacebr leetcodecom/submissions/detail/445825375/
Comment from : sayan das

what if we dont start from 0th index whenevr we call recursion and we start from the called value's index ie,brwhen we start from 2(1st level) we dont visit 1(2nd level) but start from 2 itself similarly when we start at 5 (1st level) we dont go for 1 , 2 (2nd level) and start from 5 we do this in all subsequent callbrwhat will be the time complexity for this?
Comment from : prince kumar

Thank you so much for the clear explanation!
Comment from : Minh Dang

What a good explanation Thanks a lot
Comment from : giorgi23

Sir what is the intuition for O(n) sc I mean why this algo work?
Comment from : Aakash Goswami

I just want to say thank you so much for your help Sir Your videos have been helping me so much to understand those dp problems
Comment from : Yiting G

Sir Thank you Literally, u saved me Thank you again
Comment from : Rishikesh Mishra

Thanks man you're my best friend
Comment from : Santhosh Jallu

Very nicely explained
Comment from : Divya Gowda

Hi,brI had gone through many videos regarding the same problem but wasn't able to understand how they had filled the dp table Your video made it crystal clear Thank youbrcan you tell me how do i solve the same problem if it asks for all the combinations like (1,2,2),(2,2,1),(2,1,2)-->> all these are different combinations just like the question Combination Sum 4 in leetcode
Comment from : Aparajit Chatterjee

👍
Comment from : Himanshu Singh

Solution is provided, but when explaining the dp approach, it is not so clear Seems like some paragraph reading from a coding website Please improve in why this particular approach is used and how we are moving towards it
Comment from : bharat kumar

Thanks a lot TechDose!

But what if the amount is large
Comment from : TACKLE WITH TRICKS by Kajal A

sir, if you can give ample amount of time for code walkthrough, along with explanation , that would be of much help Otherwise, your content is very good
Comment from : Anirudh Devpura

Very helpful video 😊brI see many time of interview this question was askedbrThank you so much for providing this solution
Comment from : Kunal Soni

Sir, can you give the appraoch for this question in O(n) space? I solved this question on another platform with the help of your explanation but its asking for O(n) space complexity
Comment from : Shresth Mishra

you are my best in the youtuber
Comment from : Open World

Brilliant
Comment from : Bhanu Jalan

sir can we do in o(n) space complexity
Comment from : rahul bhati

Got a really good understanding of this problem by watching this in combination with Back to Back SWE's video on this question Thanks
Comment from : Mohit Uniyal

This is beautiful

What to do if 1 1 1 1 2 and 2 1 1 1 1 are both allowed in answer?
Comment from : Mann Gondaliya

This has to be one of the best explanation of DP
Comment from : Atul Dislay

what is time complexity?

You sir, Is a GOAT 🔥
Comment from : Shiva Tomar

Good show!
Comment from : Boobalan Munusamy

Great videos man, thank you I've tried to solve this with memoization but I'm getting TLE for large inputs Can you please look at it and see if you spot some bugs? I'm not able to get it because the code works fine for small inputs leetcodecom/playground/M4RKvhZt
