Binary search is an efficient algorithm for finding a target value in a sorted array by repeatedly dividing the search interval in half. Basic Algorithm Concept Compare the target with the middle element: If equal: found If target < middle: search left half If target > middle: search right half Mathematical …

Merge sort is a stable, comparison-based sorting algorithm that uses the divide-and-conquer paradigm to sort elements in $O(n \log n)$ time. Algorithm Overview Divide and Conquer Strategy Divide: Split array into two halves Conquer: Recursively sort each half Combine: Merge the two sorted halves Mathematical …

Quick sort is an efficient, in-place, comparison-based sorting algorithm that uses divide-and-conquer. It has $O(n \log n)$ average time complexity but $O(n^2)$ worst case. Algorithm Overview Divide and Conquer Strategy Partition: Choose a pivot and partition array so that: Elements ≤ pivot are on the left Elements …
