    try to solve harder problems also :)

    if you can solve any 1000 rated problem, you can solve 800 and 900 easier and faster

      and I forgot about math :)

      the AB in div.2 are math problems

      often the ABC in div.3 are math problems

      but the ABCD in div,4 are often implementation problems

      no need to know algorithms, just math

        In div2, B almost every time is greedy
