Construct a tree structure from list of string paths

Question

I have a collection of string paths like [\"x1/x2/x3\",\"x1/x2/x4\",\"x1/x5\"] in a list. I need to construct a tree-like structure from this list which can be iterated to g

Answer 1

Just split each path by its delimiter and then add them to a tree structure one by one.
i.e. if 'x1' does not exist create this node, if it does exist go to it and check if there is a child 'x2' and so on...
