C Program to Reverse Bits of a Number – Bit Algorithm – Given an unsigned integer, reverse all bits of it and return the number with reversed bits.
Rotate bits of a number – Bit Algorithm – A rotation (or circular shift)is an operation similar to shift except that the bits that fall off at one end
Compute the integer absolute value without branching – Bit Algorithm – We need not do anything if a no is positive. We want to change only negative numbers.
Swap bits in a given number – Bit Algorithm – Given a number x and two positions (from right side) in binary representation of x, write a function that swap
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().
