Write a function to determine the number of bits you would need to flip to convert integer A to integer B.
Example1:
Input: A = 29 (0b11101), B = 15 (0b01111) Output: 2
Example2:
Input: A = 1，B = 2 Output: 2
Note:
-2147483648 <= A, B <= 2147483647
class Solution {
public int convertInteger(int A, int B) {
return Integer.bitCount(A ^ B);
}
}
