CodePath Alumni Interview Prep Class Prework

As I said in my InterviewBit profile gif, I’ve actually been using InterviewBit for about three months now (though I still have a ways to go before reaching Code Ninja status). My profile is https://www.interviewbit.com/profile/Tachyon

Checkpoint 1

Checkpoint Level 1 is just a multiple-choice question on time complexity, not a coding problem, but this repo includes a screenshot of it with my answer:

Checkpoint 2

Checkpoint 3

For some reason my profile is showing Level-Ups for Levels 1, 2, 4, and 5, but not 3, even though among other things I did the Checkpoint Level 3 prework problems below. Here also is a screenshot of the Checkpoint Level 3 screen.
