What do participants say?
“I was just surfing Codeforces blogs when I found a post about the Constructor Open Cup 2023. After discovering that I could have a chance to win a scholarship from JetBrains, I registered for the competition and placed among the top 20-30. The contest itself was very interesting, with different types of problems that allowed me to showcase my knowledge. I felt very honoured to receive a scholarship, and now I am one of the students in the BSc SDT program” – IMRUN, BSc SDT second-year student.
