The time complexity of the above solution is o(n) and requires o(n) extra space, where n is the size of the binary tree. To insert a new node in the binary tree 2. Here given code implementation process.

Print the level order of nodes in reverse order in a Binary Tree The

However, it’s possible to print the current level of the binary tree using a function in c++. Let node be the pointer to any node at level l. Function to print all nodes of a binary tree in preorder, postorder and inorder using only one stack. There are 4 ways to print the binary search tree :
