You have a single branch of a GIT or SVN repository. At some commit number G, the code in the repo worked (G = good commit). At a later commit number B, you noticed that the code was broken (B = bad). The code may have become broken anytime at or before B, but after G. B was just the first time that you noticed the code was broken. Both G and B are positive integers and G < B. You have access to a function.......bool isCommitGood(integer)......... that takes a commit number and tells you whether the code at that commit worked or was broken. Write code to find the most recent working commit (i.e., the number/index of the last good commit before the code became broken).
