WebMay 30, 2024 · Topological sorting is a post-order traversal of trees (or directed acyclic graphs). The idea is that the nodes of the graph represent tasks and an edge from A to B indicates that A has to be performed before B. A topological sort will arrange these tasks in a sequence such that all the dependencies of a task appear earlier than the task itself. WebGiven a binary tree, find its preorder traversal.
