This is going to be a complete video lecture series on Bit Manipulation covering concepts in details with implementation details and practice problems to make concepts clear and gain confidence.

Lectures (will keep updating)

L00 : Course Overview
L01 : Binary Left and Right Shift
L02 : Checking for ith Set Bit
L03 : Counting Number of Set Bits
L04 : XOR and it’s properties
L05 : All Pair Sum XOR
L06 : Total Sum of All Pair XOR

Here i will be updating the list of practice problems from different Online judges

good series

I really appreciate the videos and I’m really happy with the practise problems.
It would be nice if for every topic you cover you recommend 10-15 problems of increasing difficulty on that topic covering various sub techniques :slight_smile:

In lecture 6: Total Sum of all Pair XOR --the complexity of first for loop is logN.
can any one explain…
