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. WebApr 24, 2024 · 1. The fact that DFS does not determine uniquely the resulting labeling is due to the fact that there is no order in which the children of a node are visited. To my …
