CodeExplanation
260Generated program contains too many memory accesses.
250One or more lexer error(s).
245One or more parse error(s).
240One or more semantic error(s).
230Compiled program produced wrong output.
224AST construction is wrong.
204Compiled program not found.
124Your compiler or program timed out (your compiler or produced program might have an infinite loop).
125The MARS simulator timed out (maybe your generated program has an infinite loop).
2The MARS simulator exited prematurely.
1JVM exited prematurely. It might occur when your compiler has infinite recursion/loops, throws an uncaught exception, requires a different Java version, or when you have forgotten to push some files with git, etc.
