Online problems

The online phase of the RERS challenge has started! Below you find the six problems for the online phase, which have to be completed by October 17, 6 p.m..

NOTICE: In the integer-only-variants of the problems, the error code -2 was used instead of a silent output (-1). This has been fixed as of October 5, 2:00 a.m.. We deeply apologize for the inconvenience.

UPDATE: We have added four additional example problems, which are to be solved in the usual fashion, yet structurally slightly more complex. For self-evaluation purposes, we will publish the complete solutions for problems 10 and 11 on October 1, 2012.

A tarball with the new problems is available for download here.

Below you can find problems for all nine categories together with properties to be checked. General instructions / explanations can be found here. Additionally there is some info on the Java problems and on the C problems
