This is just a CodeForces competitive programming directory. Where we're going to code all our things. To avoid problems running in computers we have created a few things. Basically you need to create the .in and .out problems and run:
xxxx is your problem code or whatever filename you put to your xxxx.rb, xxxx.in and xxxx.out
make ruby PRG=xxxxxxxx is your problem code or whatever filename you put to your xxxx.rb, xxxx.in and xxxx.out
make cpp PRG=xxxxxxxx is your problem code or whatever filename you put to your xxxx.rb, xxxx.in and xxxx.out
make go PRG=xxxxmake solve PRG=xxxxmake clean PRG=xxxx- The ladder is an organized code forces set of problems increasing in difficulty.
