What is iterative traversal in programming?
Iterative traversal refers to the process of visiting each element in a data structure, like an array or a tree, using loops.
Can you give me an example of iterative traversal in a binary tree?
Sure! In a binary tree, you can use an in-order traversal iteratively with a stack to visit nodes in sorted order.
How does the stack help in iterative traversal?
The stack keeps track of nodes to visit next, allowing you to backtrack to parent nodes after visiting left children.
Are there other traversal methods besides iterative?
Yes, there are recursive methods as well, like pre-order, in-order, and post-order traversals.
