WebApr 6, 2024 · Map Reduce is an algorithm that can be used to search for an element in a binary search tree (BST). It is an efficient way to search for an element in a large BST. Map Reduce works by dividing the BST into two halves by using a divide-and-conquer approach. The algorithm then splits the tree into two sub-trees, one on the left side and … WebApr 10, 2024 · Algorithm to find the Cube Root using Binary Search.
