Matrix Spiral Copy

Function Name: spiralCopy

Description

Create a function that takes a 2D array (matrix) as a parameter and returns a list of its elements in spiral order.

Spiral order starts at the top-left corner of the 2D array, goes to the right, and proceeds in a spiral pattern all the way until every element has been visited.

Requirements

• The function `spiralCopy` must take exactly one parameter: a 2D array.
• The 2D array can be of any size, including empty arrays or arrays with only one row or one column.
• The function must return a list of elements in the order they were visited in the spiral.
• Do not use any built-in functions for directly converting the 2D array into a spiral order list.
• The implementation should focus on in-place traversal of the array without using extra space for another 2D array.
• The function should handle cases with rectangular matrices (not only square ones).
• Assume that the input matrix will only contain integer values.

Examples

Given the following 2D array:matrix = [
  [1, 2, 3],
  [4, 5, 6],
  [7, 8, 9]
]The function call `spiralCopy(matrix)` should return `[1, 2, 3, 6, 9, 8, 7, 4, 5]`.
