# Check whether the two numbers differ at one-bit position only in Python

Suppose we have two numbers x and y. We have to check whether these two numbers differ at one-bit position or not.

So, if the input is like x = 25 y = 17, then the output will be True because x = 11001 in binary and y = 10001. Only one-bit position is different.

To solve this, we will follow these steps −

- z = x XOR y
- if number of set bits in z is 1, then
- return True

- return False

Let us see the following implementation to get better understanding −

## Example Code

def bit_count(n): count = 0 while n: count += n & 1 n >>= 1 return count def solve(x, y): return bit_count(x ^ y) == 1 x = 25 y = 17 print(solve(x, y))

## Input

25,17

## Output

True
