Reference implementations of the joke language used in this Codeforces April Fools problem.

This is the current version used on Codeforces. The one used during contest was based on the C++ version below, but it was replaced later with a Rust rewrite due to some implementation issues.

Compile with

rustc -O checker.rs

and run with

./checker <input_file> <output_file> <answer_file>

Compile with

g++ -O2 -o checker checker.cpp

and run with

./checker <type> < <program_file>

where type is the problem ID in the Codeforces problem.

First modify the input/outputs by editing the code according to your needs. Then compile with

g++ -O2 -o interpreter interpreter.cpp

and run with

./interpreter < <program_file>
