Zig-Zag traversal of a Binary Tree using Recursion

WebA Threaded Binary Tree is a variant of a normal Binary Tree that facilitates faster tree traversal and does not require a Stack or Recursion. It decreases the memory wastage by setting the null pointers of a leaf node to the in-order predecessor or in-order successor. Recommended Topic, Binary Tree Postorder Traversal. WebThe reason this doesn't work is that res only has the value of the first node you give it appended to it; each time you recursively recall the function, it just makes a new res.

Web• A full binary tree is a binary tree such that - all leaves have the same depth, and - every non-leaf node has 2 children. • A complete binary tree is a binary tree such that - every level of the tree has the maximum number of nodes possible except possibly the deepest level. - at the deepest level, the nodes are as far left as possible.

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.
