WebSteps to invert a Binary Tree iteratively using Stack: If root/ current node is NULL, inverting is done. Define a stack S. Add root node to stack S. While stack S is not empty: 4.1. Pop node N from stack S 4.2. Swap left and right child of node N 4.3. Push new left and right child of node N to stack S. The Binary Tree is inverted. Code snippet: WebThe traversal can be done iteratively where the deferred nodes are stored in the stack, or it can be done by recursion, where the deferred nodes are stored implicitly in the call stack.

"WebWhile there are lots of ways to traverse a tree, they fall broadly into two categories: breadth-first and depth-first. The distinction, stated simply, is between the idea of working our way across before working our way downward (that's "breadth-first") and the idea of working our way downward as far as that takes us before working our way across (that's "depth-first").
