How do you find the smallest number in BST?
This is quite simple. Just traverse the node from root to left recursively until left is NULL. The node whose left is NULL is the node with minimum value.
How do you find the largest number in BST?
In Binary Search Tree, we can find maximum by traversing right pointers until we reach the rightmost node. But in Binary Tree, we must visit every node to figure out maximum. So the idea is to traverse the given tree and for every node return maximum of 3 values.
Where is the largest value in a max heap?
root node
The important property of a max heap is that the node with the largest, or maximum value will always be at the root node.
Which one is Max-Heap?
In a max-heap, the parent or root node is usually greater than the children nodes. The maximum element can be accessed in constant time since it is at index 1 . Based on the figure above, at every level, the largest number is the parent node.
Where is the smallest value in a heap?
A max-min heap is defined analogously; in such a heap, the maximum value is stored at the root, and the smallest value is stored at one of the root’s children.
How to find the largest number in BST?
Otherwise if node’s value is greater than N, then search for the element in the left subtree else search for the element in the right subtree by calling the same function by passing the left or right values accordingly. Time complexity: O (h) where h is height of BST.
Which is the smallest number greater or equal to N?
Given an integer N, the task is to find the smallest number greater than or equal to N such that it is divisible by all of its non-zero digits. Explanation: 33 is the smallest number satisfying the given condition. Explanation: 30 is the smallest number satisfying the given condition.
Which is less than or equal to N?
We have a binary search tree and a number N. Our task is to find the greatest number in the binary search tree that is less than or equal to N. Print the value of the element if it exists otherwise print -1. Recommended: Please try your approach on {IDE} first, before moving on to the solution.
What to do when the value of a node is greater than n?
Otherwise, if node’s value is greater than or equal to N and left child is NULL or less than N then return the node value. Else if node’s value is less than N, then search for the element in the right subtree. Else search for the element in the left subtree by calling the function recursively according to the left or right value.
