Minimum swap required to convert binary tree to binary search tree
Given the array representation of Complete Binary Tree i.e, if index i is the parent, index 2*i + 1 is the left child and index 2*i + 2 is the right child. The task is to find the minimum number of swap required to convert it into Binary Search Tree. Examples: Input : arr[] = { 5, 6, 7, 8, 9, 10, 11 } Output : 3 Binary tree of the given array: Swap
