omg guys. today i tried submitting competitive programming problem in Scratch, still surprised bc it can run! This is a normal thing, but to me, it's impressive. in competitions u can submit problems in Scratch. but in my whole life, i've been only submitting problems in C++ and Python. This is my 1st time submitting in Scratch!!!!!
