TODO 0054. Spiral Matrix   medium

Given an m x n matrix, return all elements of the matrix in spiral order.

Example 1:

Input: matrix = [[1,2,3],[4,5,6],[7,8,9]]
Output: [1,2,3,6,9,8,7,4,5]

Example 2:

Input: matrix = [[1,2,3,4],[5,6,7,8],[9,10,11,12]]
Output: [1,2,3,4,8,12,11,10,9,5,6,7]

Constraints:

  • m == matrix.length
  • n == matrix[i].length
  • 1 <= m, n <= 10
  • -100 <= matrix[i][j] <= 100

TODO Approach

Write your approach here.

TODO Python

class Solution:
    def spiralOrder(self, matrix: List[List[int]]) -> List[int]:

TODO C++

class Solution {
public:
    vector<int> spiralOrder(vector<vector<int>>& matrix) {
        
    }
};
