HELP

Program should read from standard input and write to standard output.

After you submit a solution you can see your results by clicking on the [My Submissions] tab on the problem page. Below are the possible results:

Accepted Your program ran successfully and gave a correct answer. If there is a score for the problem, this will be displayed in parenthesis next to the checkmark.
Time Limit Exceeded Your program was compiled successfully, but it didn't stop before time limit. Try optimizing your approach.
Wrong Answer Your program compiled and ran succesfully but the output did not match the expected output.
Runtime Error Your code compiled and ran but encountered an error. The most common reasons are using too much memory or dividing by zero. For the specific error codes see the help section.
Compilation Error Your code was unable to compile. When you see this icon, click on it for more information.
