Fill Matrix
📚RELATED PROBLEMS
Given a NxN matrix. Fill the integers from 1 to n*n to this matrix that makes the sum of each row, each column and the two diagonals equal.
Example 1:
Input: n = 2
Output: null
Explanation:We need to fill [1, 2, 3, 4] into a 2x2 matrix, which is not possible so return null.
Example 2:
Input: n = 3
Output: [[8, 3, 4], [1, 5, 9], [6, 7, 2]]
Explanation:We need to fill [1, 2, 3... 9] into a 3x3 matrix. This is one way to do it. Each row [8, 3, 4], [1, 5, 9], [6, 7, 2] sum is 15. Each column [8, 1, 6], [3, 5, 7], [4, 9, 2] sum is 15. The two diagonals [8, 5, 2] and [4, 5, 6] sum is 15.
