Programming Your Solutions
-
Programs must be in a single source file with the name specified in the problem description; failure to meet this requirement is a "Syntax or Compilation Error".
A note to Java programmers: You can still have more than one top-level classes in a single source file as long as only the main one is declared public while the rest are unqualified (i.e. just 'class', without 'public').
- Output will be judged using a file comparison utility. Output must be exactly as specified in the output format section: Spelling, punctuation, spacing, and case (uppercase/lowercase) are all significant (unless specified otherwise in the problem statement.)
-
Your program cannot require any intervention from the user. All input must be read from the input file.
If you submit a program that requires user intervention, you'll most probably receive a "Time-Limit Exceeded" error.
Contestants who have the habit of placing a "press any key to continue" statement at the end of their program should pay attention to this point.
- Do not use drive and/or path specifications when naming input files. The input file will be in the same directory as your program.
- All test cases used in judging will conform to the input specifications. There is no point for your program to try to detect invalid input or missing input file.
-
Make sure your program will compile and run using the Judges environment. Use the PC^2 test button.
