WebMar 12, 2024 · Recursive Approach: The idea is to traverse the tree in a Level Order manner but in a slightly different manner. We will use a variable flag and initially set it’s value to zero. As we complete the level order traversal of the tree, from right to left we will set the value of flag to one, so that next time we can traverse the Tree from left ... WebThe pseudocode is as follows: int binarySearch(int[] A, int low, int high, int x) { if (low > high) { return -1; } int mid = (low + high) / 2; if (x == A[mid]) { return mid; } else if (x < … easley population

Source: [Self] A binary search tree is a specific kind of tree with two major characteristics. Each node has at most TWO children — a left child and a right child. (This is why it’s called “binary.”) The left child (and all of its children) must be less than or equal to the parent.
