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 contain only values greater than the deleted node. Deletion in a binary search...

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...

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...
