## Post-order traverse of a Tree with C program.

Post-order: Post-order traverse need to traverse left, then right then root. Array, Linked List, Queues, Stacks, etc. are linear traversal where have only one logical way to traverse them. Though trees can be traversed in different ways. That Traversals:  In-order...

## C program In-order Traversal of a Tree.

In-order Traversal of a Tree. In-order traversal is very commonly used on binary search trees(BST).Tt returns values from the underlying set in order, according to the comparator set up of the binary search tree. Array, Linked List, Queues, Stacks, etc. are linear...
