You are given two numbers A and B. The task is to count the number of bits needed to be flipped to convert A to B.
Example 1:
Input: A = 10, B = 20
Output: 4
Explanation:
A = 01010
B = 10100
As we can see, the bits of A that need
to be flipped are 01010. If we flip
these bits, we get 10100, which is B.
Example 2:
Input: A = 20, B = 25
Output: 3
Explanation:
A = 10100
B = 11001
As we can see, the bits of A that need
to be flipped are 10100. If we flip
these bits, we get 11001, which is B.
Your Task: The task is to complete the function countBitsFlip() that takes A and B as parameters and returns the count of the number of bits to be flipped to convert A to B.
Expected Time Complexity: O(log N). Expected Auxiliary Space: O(1).
