Binary Search is an efficient searching algorithm used to find an element in a sorted array by repeatedly dividing the search space into half. Unlike linear search, which checks elements one by one, binary search eliminates half of the remaining elements at each step. This makes it significantly faster for large datasets. Key Requirement Binary search can only be applied when the array is already sorted. The sorting order can be: ...
Searching is the process of determining whether a given element exists in an array and, if required, returning its index. The choice of searching technique depends entirely on whether the array is sorted or unsorted. Selecting the correct approach directly impacts performance and scalability. 1. Searching in an Unsorted Array Characteristics Elements are not arranged in any specific order No assumptions can be made about element positions Linear search is the primary technique used Linear Search Concept Each element of the array is checked one by one until the target element is found or the array ends. ...
