1318. Minimum Flips to Make a OR b Equal to c

https://leetcode.com/problems/minimum-flips-to-make-a-or-b-equal-to-c

Description

Given 3 positives numbers a, b and c. Return the minimum flips required in some bits of a and b to make ( a OR b == c ). (bitwise OR operation).

Flip operation consists of change any single bit 1 to 0 or change the bit 0 to 1 in their binary representation.

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

Constraints:

• 1 <= a <= 10^9

• 1 <= b <= 10^9

• 1 <= c <= 10^9
