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 the sorted form. Binary search looks for a particular item by comparing the middle most item of the collection. WebJun 23, 2024 · Working –. 1. Search the sorted array by repeatedly dividing the search interval in half. 2. Begin with an interval covering the whole array. 3. If the value of the search key is less than the item in the middle of the interval, narrow the interval to the lower half. 4. Otherwise narrow it to the upper half.
