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.
