Susquehanna International Group Software Developer interview questions

Recruiter sent CodeSignal General Coding Framework. This website has the 4 question categories: https://codesignal.com/blog/interview-prep/example-codesignal-questions/ You are given 70 minutes to code these 4 questions. I got tripped up on the 3rd category, of 2D array traversal, as it was a bit tricky and I couldn't debug it in time. The first 2 questions are extremely easy and took me less than 15 mins, I should have went right to #4 which I prob could've also finished in less than 15 mins, but I foolishly spent all of the remaining time on #3.
