Welcome to the senior division of Cheerios Contest, a competitive programming contest series hosted by RHHS!

This contest contains 5 problems in approximately increasing order of difficulty, ranging from CCC S1 to CCC S4 level. Each problem is worth 15 points.

For RHHS students, prizes will be given to the top scores!
