Topological Sort with Nested Elements

You are given a dataset whose elements can contain references to other elements, forming a directed dependency graph. Each element must be evaluated only after all of its dependencies have been evaluated. Determine a valid order in which the elements can be calculated. It is known that topological sorting can be used to solve this kind of problem. Examples Example 1 Input: elements = [[1,2],[2,3],[3],[]] Element 0 depends on elements 1 and 2. Element 1 depends on elements 2…
