Starting with the projects I've worked on, I then moved to two coding problems. The interview took 45 minutes total, with approximately 15 minutes spent on each problem.

I didn't have enough time to finish coding the second question, but I described my approach. For the first problem, I initially found a simple solution, but it didn't cover some complex cases. Therefore, I revised my solution.

Encode a string so that any repeated characters in a row are translated to x.

For example:

abbbc => a3xbc a3xxxc => a33xxc
