We can represent the matrix with a two-dimensional array. For instance, [[1, 2, 3], [4, 5, 6], [7, 8, 9]] is an array representing the following matrix:
1 2 3
4 5 6
7 8 9
snail.js
Write and export as default a function that takes a matrix and returns an array of matrix elements in order from the top left element clockwise to the inner element. The movement across the matrix resembles a pattern on the snail shell:
Examples:
buildSnailPath([
[1, 2],
[3, 4],
]); // [1, 2, 4, 3]
buildSnailPath([
[1, 2, 3, 4],
[5, 6, 7, 8],
[9, 10, 11, 12],
]) // [1, 2, 3, 4, 8, 12, 11, 10, 9, 5, 6, 7]
