I received a call from one of the HR representatives in WA. They asked me about the core principles of OOP, the difference between overloading and overriding, and two C++ algorithm questions that weren't too difficult.

Then, the person who called inquired about a few of my projects. She seemed particularly interested in my UDF Caching project, which I completed in Scala. It appeared as though she was interested in me, but I suppose she wasn't.

You are given a string variable that holds "aabbcc". How do you output "a2b2c2" from this string?

You are given an array where each index holds either a 0 or a 1. How do you move all the 0's to the left side of the array and the 1's to the right side of the array?
