OJ is the short name of the online Judge system, which is used to detect the correctness of the program source code. The famous OJ has Rqnoj, Ural and so on. The domestic famous question Bank has the question Bank of Peking University, the Zhejiang University Question bank and so on. The foreign question bank includes the Ural University, the Varadulid University question bank and so on.

Brief introduction:

Online Judge System (referred to as OJ) is an on-line problem-solving system. Users can submit the program in a variety of programs (c, C + +) source code, the system to compile and execute the source code, and through the design of the test data to verify the correctness of the program source code.

Program:

A user-submitted program under the online Judge system will be subject to more stringent restrictions, including running time limits, memory usage restrictions, and security restrictions. The results of the user program will be captured and saved by the online judge system and then forwarded to a referee program. The referee program either compares the output data of the user program with the standard output sample, or verifies that the output data of the user program satisfies certain logical conditions. The last system returns to the user a state: Through (ACCEPTED,AC), answer error (wrong Answer,wa), timeout (time Limit exceed,tle), exceeding the output limit (outputs Limit exceed,ole), Hyper-memory (Memory Limit exceed,mle), run-time error (Runtime error,re), malformed (presentation error,pe), or unable to compile (Compile error,ce), and returns information about the memory, elapsed time, and so on used by the program.

Online Judge System was originally used in the ACM-ICPC International College Student Program Design Competition and Oi Informatics Olympic competition in automatic judgment and ranking. It is widely used in the training of program design of college students all over the world, the training and selection of participants, the competition of various program designs, the study of data structure and algorithm, and the automatic submission judgment of homework.
