Suppose there is an array, A, which can be sorted if that information helps.
We have multiple arrays, B, C, D, etc., all sortable and potentially overlapping with array A.
The objective is to identify the smallest combination of arrays B, C, D, etc., which completely overlap with array A. The function should return the first matching set.
For example:
const A = [1, 2, 3, 4, 'a', 'b', 'c'];
const B = [1, 3, 4, 5, 10];
const C = [1, 3, 5, 'a', 'b']
const D = [2, 4, 'a', 'b', 'c'];
const E = [1, 2, 'b', 'c']
findSmallestSet(A, [B, C, D, E]);
// => [B, D]
Note: Initially, the problem was about identifying node trees fully encompassing a target node tree. However, this simplified version might offer a more straightforward solution.
