No background questions, only the code questions.

The first one was a run-length decoder. I had to call a function named iterate and write this function. The interviewer was not as patient as I thought.

The second question was a binary search, which was quite easy.

The third question also involved a string and was not very difficult.

I spent a lot of time on the first one, trying to understand how to decode, and did not communicate with the interviewer well.

Create a run-length decoder. Call this function iterate and write this function.
