# Official Released Competition Problems » Code Clash 2019

2019 was the inaugural year of the Code Clash high school programming competition. Ponaganset High School held a contest between ten teams of four students in which they had to solve eleven challenging problems. The contestants only had two and a half hours to complete as many of the problems as they could (it is obviously impossible to complete all of them in 150 minutes).
