Submission 1: Number bases and binary search

[Sukhrobjon]

1. Number bases: Excellent work. Good documentation and comments.
2. Binary search: Your code looks good and working all well. But I recommend you look at how your peers implemented binary search, seems like your implementation a bit too complicated. You are using a little more checks: if clause in your code.

Thanks for the notice @Sukhrobjon ! I refactored that if-else block, it should be cleaner now.
