You are given a binary tree whosekeys are integers. You need to test if this is a correc tbinary search tree. The rule is like this, the first number (firstline) will show how manynodes there will be.The following lines will have 3 integers: the key of the node (key), the index of left child and (left) and the index of right child (right). -1 means there is no child of the node. OUTPUT: If the given binary tree is a correct binary search tree, then “it is a binary search tree” will be printed. Otherwise, “it is not a binary search tree” will be printed. Example: Input 3 4-1- 2 2 -1 -1 5 -1 -1   Output: it is a binary search tree Example 2: Input: 3 5 -1- 1 7 -1 -2 9 -1 -1 Output:it is a binary search tree Use C language for writing your code

Question
  • You are given a binary tree whosekeys are integers. You need to test if this is a correc tbinary search tree. The rule is like this, the first number (firstline) will show how manynodes there will be.The following lines will have 3 integers: the key of the node (key), the index of left child and (left) and the index of right child (right). -1 means there is no child of the node.

OUTPUT: If the given binary tree is a correct binary search tree, then “it is a binary search tree” will be printed. Otherwise, “it is not a binary search tree” will be printed.

Example: Input

3

4-1- 2

2 -1 -1

5 -1 -1

 

Output: it is a binary search tree

Example 2:

Input:

3

5 -1- 1

7 -1 -2

9 -1 -1

Output:it is a binary search tree

Use C language for writing your code
