We do this recursively to benefit from the fact … WebBreadth First Search is generally the best approach when the depth of the tree can vary, and you only need to search part of the tree for a solution. For example, finding the shortest path from a starting value to a final value is a good place to use BFS. Depth First Search is commonly used when you need to search the entire tree.

WebMy plan is to use two stacks. One for pre-order traversal and another one is for post-order traversal. Now, I run standard iterative DFS (depth-first traversal), and as soon as I pop from the "pre" stack i push it in "post" stack. At the end, my "post" stack will have child node at top and and root at bottom. Web题目链接 Description You are given an undirected tree consisting of nnn vertices.
