In St Petersburg phone numbers are formatted as “XXX–XX–XX”, where the first three digits represent
index of the Automated Telephone Exchange (ATE). Each ATE has exactly 10000 unique phone numbers.
Peter has just bought a new flat and now he wants to install a telephone line. He thinks that a phone
number is lucky if the arithmetic expression represented by that phone number is equal to zero. For
example, the phone number 102–40–62 is lucky (102 - 40 - 62 = 0), and the number 157–10–47 is not
lucky (157 - 10 - 47 = 100 ≠ 0).
Peter knows the index of the ATE that serves his house. To get an idea of his chances to get a lucky number he wants to know how many lucky numbers his ATE has.
The input file contains several test cases. It ends with EOF.
Each test case contains a single integer number n — the index of Peter’s ATE (100 ≤ n ≤ 999).
Output a single integer number — the number of lucky phone numbers Peter’s ATE has.
