Binary tree inorder traversal python

WebThe binary tree could be constructed as below. A given pre-order traversal sequence is used to find the root node of the binary tree to be constructed. The root node is then used to find its own index in the given inorder traversal sequence. This is needed for constructing the left and the right sub-trees of the root node. WebThus, there are two types of skewed binary tree: left-skewed binary tree and right-skewed binary tree. Skewed Binary Tree 6. Balanced Binary Tree.
