Simplified boolean logic?

[SeanPMulligan]

First off, thank you so much for all the time and effort building and maintaining this repo. It's been a huge boon to my learning in problem solving and algorithmic approaches. I had one small comment regarding one of the C++ solutions. For the problem string_integer_interconversion could the following assignment be simplified from

  bool is_negative = false;
  if (x < 0) {
    is_negative = true;
  }

to:

  bool is_negative = x < 0;

Again thanks to all the maintainers for your work 🎉
