}elseif(val >root.val) {//if delete value is larger than root, search on right side of treeroot.right =deleteNode(root.right, val); }elseif(val <root.val) {//if delete value is smaller than root, search on left side of treeroot.left =deleteNode(root.left, val); }else{//if ...
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, ...
function Node(val) {return{ val, left:null, right:null}; } function Tree() {return{ root:null, addLeft(val, root) {constnode =Node(val); root.left=node;returnroot.left; }, addRight(val, root) {constnode =Node(val); root.right=node;returnroot.right; ...

Thetwalksubroutine steps through the binary search tree whose root is pointed to by theRootPointerparameter. (Any node in a tree can be used as the root to step through the tree below that node.) TheActionparameter is the name of a routine to be invoked at each node. The routine specif...
