If number of nodes are even: then median = ( (n/2th node + ( (n)/2th+1) node) /2 If number of nodes are odd: then median = (n+1)/2th node. Examples: Input: Example of BST Output: median of Below BST is 6. Explanation: Inorder of Given BST will be 1, 3, 4, 6, 7, 8, 9 So, here median will 6.

In real life, binary search can be applied in the dictionary. Binary search is also used to debug a linear piece of code. Binary search is also used to find if a number is a square of another or not.
WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until …
WebThe recursive method of binary search follows the divide and conquer approach. Let the elements of array are - Let the element to search is, K = 56 We have to use the below formula to calculate the mid of the array - mid = (beg + end)/2 So, in the given array - beg = 0 end = 8 mid = (0 + 8)/2 = 4. So, 4 is the mid of the array.
