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
给你三个正整数 a、b 和 c。
你可以对 a 和 b 的二进制表示进行位翻转操作，返回能够使按位或运算 a OR b == c 成立的最小翻转次数。
「位翻转操作」是指将一个数的二进制表示任何单个位上的 1 变成 0 或者 0 变成 1 。
示例 1：
输入：a = 2, b = 6, c = 5
输出：3
解释：翻转后 a = 1 , b = 4 , c = 5 使得 a OR b == c
示例 2：
输入：a = 4, b = 2, c = 7
输出：1
示例 3：
输入：a = 1, b = 2, c = 3
输出：0
提示：
1 <= a <= 10^9
1 <= b <= 10^9
1 <= c <= 10^9
