WebDec 21, 2024 · Time Complexity: O(n), As it does two inorder traversals of the binary tree. Auxiliary Space: O(n), The extra space is used to store the odd level nodes of the tree and in recursive function call stack which is O(h), where h is the height of the tree. Method 3 (Using One Traversal): This method simply swaps the values of the children node, if the … WebBinary Tree. When every non-leaf node in a tree has atmost 2 children, its called a binary tree. Given below is an example of a binary tree. Inversion of a Binary tree. Inverting a binary tree is producing another binary tree as output where all the left and right nodes of all non-leaf nodes of the original binary tree are interchanged.
