WebApr 10, 2024 · Binary Search. Binary search is an algorithm used to find an element i.e., key in a sorted array. Binary algorithm works as below . Let us say that array is ‘arr’. Sort the array in ascending or descending order. Initialize low = 0 and high = n-1 (n = number of elements) and calculate middle as middle = low + (high-low)/2. WebBinary search is a fast search algorithm with run-time complexity of Ο (log n). This search algorithm works on the principle of divide and conquer. For this algorithm to work properly, the data collection should be in a sorted form. Implementation in C Live Demo
WebApr 11, 2024 · Step 1 − Start. Step 2 − Mid element collection calculation. Step 3 − Compare the key with a mid-element. Step 4 − If, the value of key and mid element both are same; then Return the result. Step 5 − Else, the value of key is greater than mid element, follow right half collection. Step 6 − Or; if the value of the key is less than ... WebApr 5, 2024 · A binary search is a simplistic algorithm intended for finding the location of an item stored in a sorted list.
