Problem:
 Score: 100 points    Problem 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   What kyu does M-kun have?      Constraints   400 \leq X \leq 1999  X is an integer.         Input  Input is given from Standard Input in the following format:  X       Output  Print the kyu M-kun has, as an integer.
For example, if he has 8 -kyu, print 8 .        Sample Input 1 725      Sample Output 1 7  M-kun's highest rating is 725 , which corresponds to 7 -kyu. Thus, 7 is the correct output.       Sample Input 2 1600      Sample Output 2 2  M-kun's highest rating is 1600 , which corresponds to 2 -kyu. Thus, 2 is the correct output.
