2133 - Check if Every Row and Column Contains All Numbers.

Easy

An n x n matrix is valid if every row and every column contains all the integers from 1 to n ( inclusive ).

Given an n x n integer matrix matrix, return true if the matrix is valid. Otherwise, return false.

Example 1:

Input: matrix = [[1,2,3],[3,1,2],[2,3,1]]

Output: true

Explanation: In this case, n = 3, and every row and column contains the numbers 1, 2, and 3. Hence, we return true.

Example 2:

Input: matrix = [[1,1,1],[1,2,3],[1,2,3]]

Output: false

Explanation: In this case, n = 3, but the first row and the first column do not contain the numbers 2 or 3. Hence, we return false.
