$complexity theory - Why does binary search take $O(\log n)$

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.
