1318. Minimum Flips to Make a OR b Equal to c
Medium
30 Points
Bit Manipulation
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.
Examples
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 <= 10^91 <= b <= 10^91 <= c <= 10^9
