Hello codeforces, I am not able to hack solutions of Educational Round 93. When I click on hack it forwards me to hacks page but nothing happens. Is it me or you guys also facing the issue?
Hii All! I am practicing for 3 months on the codeforces and still I am unable to solve B and C problems in running Div2 contests, what data structures and algorithms should I learn for becoming able to solve B and C problems or especially for C. Sorry for my bad English, this is not my first language.
