Solution for GCJ problems. The templates that I use are: GCJ2018_Problem.cs (for CSharp) and solverTemplate.txt (for C/C++).
I switched from C to C# as the main language to speed-up development. The practice problems use multiple files (base solver classes), but for the contest single files must be used (basically copy and rename GCJ2018_Problem.cs.
Contains the qualification problems and some solutions for round 1 (C/C++).
