Largest Subarray with 0 Sum | Hashmap & Heaps | Data Structure & Algorithms

[@satyamgupta6030]

sir I can't believe seriously how can someone teach so so well. I have watched videos of other popular youtubers as well but no one comes even close to you. hats off. since pepcoding is bought by scaler I'll always miss your teachings.

[@astuteToddler]

after putting (0,-1) we dont require to check if the element is 0 itself, which is done in another videos. It makes thing more complicated whereas this trick is great and simplifies everything. Thanks a lot for it!

[@ommapari]

Yes they way, it makes soluation more simpler

all good, keep it up. just try to add complexity as well since it is a very important aspect. and alternate efficient solutions

Thank u sir ❤❤❤

[@ADITIDANA]

great explanation👍

[@anshumanpanda8887]

at index i=0 the sum will always be equal to the element present at i=0. So instead of i=-1,and sum =0. We can store sum =ar[0] and start the loop like for(int i=1;i

[@ajeetworking]

thanks, Sumit Bhai...best explanation.

[@varunmanchanda3972]

Sir, I have just observed one thing that mostly "subarray" questions are solvable using Hashmap, is it true somewhere, or Intuition changes over questions?

[@Pepcoding]

beta, safe assumption hai.

[@varunmanchanda3972]

@@Pepcoding Sir, while solving questions by this technique, I thought can we solve these questions using divide and conquer because subproblem is of same type of we divide our whole big problem?

[@rohitshirur7640]

@@varunmanchanda3972 in some of problems we use window sliding technique

Sliding Window, Prefix sums and Hashing three approaches are most common

Just add these two lines and it will pass all test cases like this: if(A[i]==0) ans = max(ans, i+1);
