A layout engine can nest grids: a page of n tiles might be 2 groups of 6, or 2 groups of 2 groups of 3. Each nesting is a way to write n as a product of two or more whole numbers, each at least 2.
Write factorLayouts(n) that returns every such product as an array of factors in non-decreasing order. List the arrays in sorted order: compare first factors, then second factors, and so on.
If n can't be written this way (for example 1 or a prime), return [].
Input: n = 12 Output: [[2,2,3],[2,6],[3,4]]
12 = 2 × 2 × 3 = 2 × 6 = 3 × 4. 12 alone doesn't count, since it needs two or more factors.
Input: n = 7 Output: []
7 is prime, so it can't be split into smaller factors.

I'm here to help with #306 Factor Grid Layouts. I give hints, never the solution, so you get to solve it yourself. Ask for a hint, select code to ask about it, or press Ask Tuto why on a failing test.
