problem_description: Statement
  
  M-kun is a competitor in AtCoder, whose highest rating is X.  
  In this site, a competitor is given a _kyu_ (class) according to his/her
  highest rating. For ratings from 400 through 1999, the following kyus are
  given:
  
    * From 400 through 599: 8-kyu
    * From 600 through 799: 7-kyu
    * From 800 through 999: 6-kyu
    * From 1000 through 1199: 5-kyu
    * From 1200 through 1399: 4-kyu
    * From 1400 through 1599: 3-kyu
    * From 1600 through 1799: 2-kyu
    * From 1800 through 1999: 1-kyu
