Competitive Coding -- 2

Hello! I'm looking for an experienced coder to help me with some competitive coding problems. I prefer C++ as the programming language, but I'm open to any technology that will help me reach my goal. My difficulty level is set at intermediate, so only experienced coders need apply. Additionally, I have multiple coding problems I'd like to solve, so having experience with a wide range of coding topics would be beneficial. If you're up to the challenge then I'd love to hear from you!
