WebNov 16, 2024 · A binary search tree (BST) adds these two characteristics: Each node has a maximum of up to two children. For each node, the values of its left descendent nodes are less than that of the current node, which in turn is less than the right descendent nodes (if any). The BST is built on the idea of the binary search algorithm, which allows for ... WebThe major difference between the iterative and recursive version of Binary Search is that the recursive version has a space complexity of O (log N) while the iterative version has a space complexity of O (1). Hence, even though recursive version may be easy to implement, the iterative version is efficient. shania twain ancestryWebint binarySearch(int[] A, int x) { int low = 0, high = A.length - 1; while (low <= high) { int mid = (low + high) / 2; if (x == A[mid]) { return mid; } else if (x < A[mid]) { high = mid - 1; } else { low = mid + 1; } } return -1; } Let us get started with the mathematical analysis of Binary Search.
