in generic tree represented common node structure having parent , child pointers, how can 1 find list of paths have no overlapping edges each other , terminate leaf node. for example, given tree this: 1 / | \ 2 3 4 / \ | / \ 5 6 7 8 9 the desired output list of paths follows: 1 2 1 1 4 | | | | | 2 6 3 4 9 | | | 5 7 8 or in list form: [[1, 2, 5], [2, 6], [1, 3, 7], [1, 4, 8], [4, 9]] obviously path lists , order can vary based on order of processing of tree branches. example, following possible solution if process left branches first: [[1, 4, 9], [4, 8], [1, 3, 7], [1, 2, 6], [2, 5]] for sake of question, no specific order required. you can use recursive dfs algorithm modifications. didn't language use, so, hope c# ok you. let's define class our tree node: public class node { public int id; public bool usedonce = ...
