Merge Sort Using Divide and Conquer

Algorithm (Interview-Oriented Pseudocode) This pseudocode is intended to help learners understand and explain the algorithm and develop their own solution. Code Output Similar Topics The main function takes user inputs for an array and a key to search for.The binarysearch function is a recursive implementation that splits the array in half, comparing the middle element

Binary Search Using Divide and Conquer

Pseudo Code Algorithm for Binary Search. This is a recursive implementation of a Binary Search algorithm using the Divide and Conquer technique. Binary Search is efficient for finding an element in a sorted array, with a time complexity of O(log⁡*n). Explanation of Pseudo Code: Function: BinarySearch(array, low, high, key) Parameters: Base Case: (Check if low
