WebWhen we binary search on an answer, we start with a search space of size N N which we know the answer lies in. Then each iteration of the binary search cuts the search space in half, so the algorithm tests \mathcal {O} (\log N) O(logN) values. This is efficient and much better than testing each possible value in the search space. WebJul 25, 2024 · It's a bad idea to hide the built-in list. I renamed the parameter to lst, which is commonly used in Python in this situation. mid = (low + high) // 2 is a simpler form of finding the midpoint. Python convention is to use snake_case, not camelCase, so I renamed the function. Fixed code:
