Hello Codeforces Community,
I have recently turned expert in the previous educational round. And now seek advice on how to conquer the next step — Turning Purple
I have solved lots of questions in the 1400 to 1500 range which helped me in consistently solving A B and C in almost every Div 2 contest. Whenever i attempt a 1700 — 1800 problem it seems way too difficult from what i have previously solved.
Are there some advanced algorithms or concepts i need to learn before practicing to conquer the next step ? Or spamming practice is the answer ?
