WebMar 22, 2024 · For example, O(2N) becomes O(N), and O(N² + N + 1000) becomes O(N²). Binary Search is O(log N) which is less complex than Linear Search. There are many more complex algorithms. A common example of a quadratic algorithm or O(N²) is a nested for loop. In a nested loop, we iterate through the entire data in an outer loop. WebBinary search is an efficient algorithm for finding an item from a sorted list of items. It works by repeatedly dividing in half the portion of the list that could contain the item, until you've narrowed down the possible locations to just one.
