A *full binary tree* is a binary tree where each node has exactly 0 or 2 children. Return a list of all possible full binary trees withNnodes. Each element of the answer is the root node of one possible tree. Eachnodeof each tree in the answer must havenode.val = 0. You may ret...

we should know that it is not a normal pattern problem, we cannot traverse to solve the problem. Since we need to go it in linear…(I do not know how to describe). We assume that solve(X) is the list of all possible tree, then from the N node, we have left subtree withinode a...
