Binary search code in java
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. Let us consider the problem of searching for a word in a dictionary. WebMar 8, 2024 · Here are the steps involved with the binary search algorithm: Step #1 - Sort the Array In order to start the search, you'll need to have a sorted array.
