Program-Autograding-Server-DECS

step-by-step construction of a scalable program autograding server and its client We assume that the purpose of the submitted program is simply to print the first ten numbers: 1 2 3 4 5 6 7 8 9 10 If the submitted program prints this output, it has passed, else it has failed. In all versions, the server will always be run as follows, $./server and the client will always be run as follows, $./submit serverIP:port and will get back one of the following responses from the server:

1. PASS
2. COMPILER ERROR
3. RUNTIME ERROR
4. OUTPUT ERROR In cases 2,3,4, the server should additionally send back the error details: ● For compiler error, the entire compiler output should be sent back to the client ● For runtime error, the error type should be sent back to the client ● For output error, the output that the program produced, and the output of a ‘diff’ command should be sent back to the client
