When a node is deleted, the binary search property of the tree must be preserved, i.e. that the left subtree of the deleted node must contain only values less than the deleted node, and the right subtree must c
}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 ...
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, just return itifnotroot:returnroot# Find the node in the left subtree if key ...

Search for a node to remove. If the node is found, delete the node. Note:Time complexity should be O(height of tree). Example: 代码语言:javascript 代码运行次数:0 root=[5,3,6,2,4,null,7]key=35/\36/\ \247Given key todeleteis3.So we find the nodewithvalue3anddeleteit.One valid...
