I don't like bit manipulation at all

Do you hate it more than dynamic programming? I can some what come close to a solution for bit manipulation problems but I can't understand dp solutions even after watching the explanation multiple times.

@@AnordinaryMan007 to be able to solve dp problems on my own do I need to solve enough problems in order to reach the moment where it all clicks? Do you have any suggestions?

these are interesting questions, however bit manipulation questions just feel like one trick pony solutions (much like greedy). interesting but not satisfying sadly.

I agree, I don't think I've ever been asked bit manipulation in an interview. Has anyone here been asked it?

You flipped the 3 and 5 in a and b.. But the concept is clear.. Thanks neetcode!

Had to rewind back multiple times but the grouping still didn't make sense. This comment cleared my doubt. Should have been the top comment😅

@csam11100 3 ай бұрын

The a-ha moment is the grouping concept. Feel depressed even practicing more than a thousand of LC, still can not get it in an hour and open YT to watch your solution like I did 4 years ago. (BTW, we can use xor & -xor to find the right most set bit of xor) Appreciate your explanation as usual.

Hey Navdeep, first of all a huge thank you for making videos and helping us throughout the journey of DSA. I would like to request you to make LC bi weekly and weekly contest solutions as well. The questions in contests contain different gravy and it'll help us be more prepared for interviews... Cheers🎉
