Spiral Matrix: coding question

Problem

You get a matrix matrix with m rows and n columns. A matrix is a grid of numbers. Return all the items of the matrix in spiral order.

Spiral order starts at the top-left item and moves right along the top row. Then it moves down the right column, left along the bottom row and up the left column. Then it does the same steps on the remaining inner part, until it visits each item.

Example 1

Input:: matrix = [[2,4,6],[8,10,12]]
Output:: [2,4,6,12,10,8]
Explanation:: The top row gives 2, 4 and 6. The right column gives 12, and the bottom row, from right to left, gives 10 and 8.

Example 2

Input:: matrix = [[3,1,4],[1,5,9],[2,6,5]]
Output:: [3,1,4,9,5,6,2,1,5]
Explanation:: The outer ring gives 3, 1, 4, 9, 5, 6, 2 and 1. The center item 5 comes last.

Example 3

Input:: matrix = [[7],[8],[9]]
Output:: [7,8,9]
Explanation:: The matrix has one column, so the order goes from top to bottom.

Constraints

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