Interview Course Based on Story Questions

# Problem statement
The latest version of a software product fails the quality check. Since each version is developed upon the previous one, all the versions created after a bad version are also considered bad.
Suppose you have `n` versions with the following IDs:`[1, 2, ..., n]`. Your task is to find the first bad one, which is causing all the later ones to be bad. 

Consider that you have the access to an API call, `is_bad_version(ID)`, that returns `True` if the argument is the ID of a bad version. You have to implement a solution with the minimum number of API calls.
