In in-order traversal, we traverse the left child and its sub-tree (s), then we visit the root and then traverse the right child and its sub-tree (s). It takes a “left-root-right” order. Before we take a look at a code sample for this algorithm, let’s try to outline the steps involved:

WebUnderstanding the below given iterative traversals can be a little tricky so the best way to understand them is to work them out on a piece of paper. Use this sample binary tree and follow the steps of the below given codes.
