A program to check if a Binary Tree is BST or not

WebSuppose if we change the value of node 35 to 55 in the above tree, check whether the tree will be binary search tree or not. In the above tree, the value of root node is 40, which is greater than its left child 30 but smaller than right child of 30, i.e., 55. So, the above tree does not satisfy the property of Binary search tree. Web1. Check the in-order traversal. If the in-order traversal of the Binary Tree is sorted in ascending order, then the tree is Binary Search Tree, else it is not Binary Search Tree. Code: I am using the code from this post. The function populates the inorder traversal of the tree in an array. WebSep 27, 2024 · This is simple we just check if both left and right are None. def is_symmetric (node): return node.left is None and node.right is None assert is_symmetric (Node (None)) We get a tree with 3 nodes working. The simplest way to do this is to just check if left and right's value are the same ignoring if either are None. card shop kenilworth
