How do you delete an element from a binary search tree?

How do you delete an element from a binary search tree?

Algorithm

  1. Step 1: IF TREE = NULL. Write “item not found in the tree” ELSE IF ITEM < TREE -> DATA. Delete(TREE->LEFT, ITEM) ELSE IF ITEM > TREE -> DATA. Delete(TREE -> RIGHT, ITEM) ELSE IF TREE -> LEFT AND TREE -> RIGHT. SET TEMP = findLargestNode(TREE -> LEFT) SET TREE -> DATA = TEMP -> DATA.
  2. Step 2: END.

Can you have a binary search tree of strings?

A BST is a binary tree that satisfies the following properties for every node: The left subtree of the node contains only nodes with keys lesser than the node’s key. The right subtree of the node contains only nodes with keys greater than the node’s key. The left and right subtree each must also be a binary search tree …

How do you delete a node with two child nodes from a binary search tree?

1) Node to be deleted is the leaf: Simply remove from the tree. 3) Node to be deleted has two children: Find inorder successor of the node. Copy contents of the inorder successor to the node and delete the inorder successor. Note that inorder predecessor can also be used.

When deleting an element in a binary search tree there are three cases to consider in the space below state what the three cases are?

Here are the three cases that arise while performing a delete operation on a BST:

  • Case 1: Node to be deleted is a leaf node. Directly delete the node from the tree.
  • Case 2: Node to be deleted is an internal node with two children.
  • Case 3: Node to be deleted is an internal node with one child.

How do you convert strings to trees?

Construct Binary Tree from String in C++

  1. Define a function solve(), this will take s, idx,
  2. if idx >= size of s, then −
  3. num := empty string.
  4. while (idx < size of s and s[idx] is not equal to ‘(‘ and s[idx] is not equal to ‘)’), do −
  5. node = new node with value num.
  6. if idx < size of s and s[idx] is same as ‘(‘, then −

How do you search elements in a binary search tree?

Algorithm to search an element in Binary search tree

  1. Search (root, item)
  2. Step 1 – if (item = root → data) or (root = NULL)
  3. return root.
  4. else if (item < root → data)
  5. return Search(root → left, item)
  6. else.
  7. return Search(root → right, item)
  8. END if.
