Approach1:
Simple algorithm
- n := row count of matrix
- if n <= 2, then
- return sum of all elements in matrix
- first_row := sum of first row
- last_row := sum of last row
- diagonal = sum of matrix[i, n-1-i] for all i from 1 to n-2
- return first_row + last_row…
Given two integers x, and y return the number of positions where their values differ in their binary representations as a 32-bit integer.

Input
x = 9
y = 5…
