What is the difference between lower bound and tight bound?
...ga notation).
If I were lazy, I could say that binary search on a sorted array is O(n2), O(n3), and O(2n), and I would be technically correct in every case. That's because O-notation only specifies an upper bound, and binary search is bounded on the high side by all of those functions, just not v...

If you are dealing with numpy arrays or can afford numpy as a dependency, consider also using
import numpy as np

This will be faster than the first solution even if you apply it to a pure Python list if:
it is larger tha...

How do I sort a Set to a List in Java?
...e best. It is inefficient, as it creates a new List and an unnecessary new array. Also, it raises "unchecked" warnings because of the type safety issues around generic arrays.
Instead, use something like this:
