Here is something you might want to ask yourself after watching this video: What if the initial array given to us is not filled with 0s, would this technique still work? If not, how will you modify it so that it still works.

I was using this from earlier, but today I knew that it is called difference array.

[tarunmali]

Please keep bringing similar small videos!!!!

[parthchaturvedi]

Very informative priyansh, keep posting such videos

[AbhishekKumar-wxrw]

the bullet example was great i immediately got why we are doing the process after that example

[yashhokte]

Hats off to you man✨️ You explained this technique in a very simple manner✨️

[harshsankalp]

Hi priyansh, few days ago you posted questions on Time & space complexity on twitter & I was not able to find the right answer. Probably a detailed video on time & space complexity would really help everyone. Also, how to analyse which algorithm would be suitable based on the inputs & constraints. Some standard TC of the loops, how to go about finding the TC & SC etc.
