Check if Every Row and Column Contains All Numbers
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
1 2 3 3 1 2 2 3 1
Input
matrix = [[1,2,3],[3,1,2],[2,3,1]]Output
trueIn this case, n = 3, and every row and column contains the numbers 1, 2, and 3, so we return true.
Example 2
1 1 1 1 2 3 1 2 3
Input
matrix = [[1,1,1],[1,2,3],[1,2,3]]Output
falseIn this case, n = 3, but the first row and the first column do not contain the numbers 2 or 3, so we return false.
Constraints
- n == matrix.length == matrix[i].length
- 1 <= n <= 100
- 1 <= matrix[i][j] <= n
