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.
Constraints:
n == matrix.length == matrix[i].length
1 <= n <= 100
1 <= matrix[i][j] <= n
