WebDec 1, 2024 · Solution 1: Iterative Intuition: In preorder traversal, the tree is traversed in this way: root, left, right. When we visit a node, we print its value, and then we want to visit the left child followed by the right child. The fundamental problem we face in this scenario is that there is no way that we can move from a child to a parent.
