Description

Given three positive integers a, b, and c, a single flip changes one bit in a or b from 0 to 1 or from 1 to 0. Return the minimum number of flips required so that a OR b equals c (using bitwise OR).

Example 1:

Input: a = 2, b = 6, c = 5
Output: 3
Explanation: After flips a = 1 , b = 4 , c = 5 such that (a OR b == c)

Example 2:

Input: a = 4, b = 2, c = 7
Output: 1

Example 3:

Input: a = 1, b = 2, c = 3
Output: 0
