xor

Problem You are given two numbers A and B. Write a function to determine the number of bits need to be flipped to convert integer A to integer B. Example Input: 73, 21 Output: 4 Representing numbers in bits : A = 1001001 B = 0010101 C = \* \*\*\* C = 4 Solution Method 1 - Counting the bits set after XORing 2 numbers 1. Calculate XOR of A and B. [Read More]
