Grader and custom test make different output. Is it server's bug?
By afrizal, 10 years ago, In English

Hello everyone

I had submitted some solutions on 443C. They got WA on test 3 (even after I use 2 different languages, cpp and java). But when I tested in my compiler (g++ 4.8.1 and JDK 1.7.0), custom invocation on CF, and even ideone.com, they make correct output.

Could someone tell me whats happened? Thank you for your help

C++ submission : 6934350

Tested in ideone.com

Java submission : 6936214

Tested on ideone.com

welp, on my machine and custom invocations for Java 7/8 and c++ return integer.max_value for the third sample test case. Are you sure you haven't changed anything in source code?

edit: I re-run your code on ideone again, and it does output integer.max_value. http://ideone.com/n6EuzN

    Making your class public breaks it for some reason.

      I'm sure i don't change anything. Also i've changed class to public and still output 4

      edit : this code works well in public class http://ideone.com/zZ0l5e

        The test case you are using is obviously different (i.e. your code doesn't handle the third sample correctly). Why would you test with a different test code on ideone, and confuse others?

You've run the problem on a different testcase on ideone.
