Learn how to do deletion in a binary search tree using C++, its time complexity, and why deleting a node in BST is difficult.
Note: Search for a node to remove. If the node is found, delete the node. Sample Solution: Python Code: # Definition: Binary tree node.classTreeNode(object):def__init__(self,x):self.val=x self.left=Noneself.right=Nonedefdelete_Node(root,key):# if root doesn't exist, ...

case 1: if the delete node is leaf node, then we can simply remove it case 2: if the delete node is has single side or substree case 3: it has two children, then to keep it as a valid binary search tree, we can copy the min value from right subtree to delete node, to convert...

binary search tree. Like thetsearchsubroutine, thetfindsubroutine searches for a node in the tree, returning a pointer to it if found. However, if it is not found, thetfindsubroutine will return a null pointer. The parameters for thetfindsubroutine are the same as for thetsearchsubroutine...
