Next higher number with same number of set bits – Bit Algorithm – When we observe the binary sequence from 0 to 2n – 1 (n is # of bits),The idea is to find right most string of 1’s in x, and shift the pattern to right extreme
Program to count number of set bits in an (big) array- Bit Algorithm – The simple approach would be, create an efficient method to count set bits in a word.
Count total set bits in all numbers from 1 to n – Bit Algorithm – In other words, if the control goes inside while loop of getNextLeftmostBit().
