For Prefix sum we need one check as if i=0 then prefix sum is array[j]

Great article! Completely agree with your points. One question- sometimes identifying the pattern can be difficult because one problem can have many patterns, and sometimes problems are tricky, so how do you get around that?

Love your work and hope to see more from you soon :)

It takes some practice to be able to identify the right pattern for the problem at hand.

For tricky problem, it might be a good idea to brainstorm multiple patterns and see which one fits.

As an example a lot of the subarray problems with prefix sum based solution also seem like a sliding window type problem. Any tips on differentiating those?

Damn this is Gold. Great for revision, I made notes watching the YT video and found this at last 🥲, took a lot of time. Ashish bhai i need your help, i am preparing for Google New Grad 2025. some personal advice or tips to crack the interview rounds would mean a lot.

Can you also add one sample code implementation for the patterns with the best approach. Then it will be all at one place.
