WebSearching, one of the most fundamental problems in computer science, is well accomplished with recursive techniques. We will look at two algorithms for searching: linear search and binary search. Linear search operates by looking sequentially through data, comparing the current element to the search element. WebJul 4, 2024 · The element has been found at index 6 A class named Demo contains the binary search function, that takes the left right and value that needs to be searched.

"WebBinary Search algorithm is used to search an element in a sorted array. Binary search works by comparing the value to the middle element of an array. If the value is found then index is returned otherwise the steps is repeated until the value is found. It is faster than linear search. Time complexity of Linear search is O (n).
