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. WebNov 29, 2024 · Depth-First Search Algorithm. The Depth-First Search (also DFS) algorithm is an algorithm used to find a node in a tree. This means that given a tree data structure, the algorithm will return the first node in this tree that matches the specified condition (i.e. being equal to a value). Nodes are sometimes referred to as vertices …
