Cambodia CS Cup is an annual competitive programming competition organized by several Cambodian universities (Royal University of Phnom Penh, University of Puthisastra and Paragon International University) and partners (KhmerCoders Community, company Slash, company Mango Byte) where high school and university students compete against each other as individuals rather than in teams.

Students have to solve algorithmic problems to advance through up to four rounds of programming challenges.
