Code Execution

[cheehongw]

Possible implementation for a code executor would be a pipeline architecture:

(user program )                
         +         --> code executor ---> (program output/err) 
(qn's .in files) 

----------------------------------------------------------------

(program output/err)                
         +            --> verifier ---> (solve status + program output/err)
  (qn's .out files) 

Then all we need to do is to supply the backend with the user's program and its metadata, the .in files and .out files
