Billy, as well as most of you, was born in the 80's. The 2980's, that is. He likes his decade so much, he wants to know how many years in a given year range correspond to some specific decade.
For instance, if he wanted to know how many 80's years have happened from 1986 through 2082, the answer would be 7: 1986, 1987, 1988, 1989, 2080, 2081, and 2082. Given a closed interval representing years, find out how many years are in a given decade.
The first line of the input consists of a single number, N (1 ≤ N ≤ 50), the number of test cases to follow. Each test case consists of a single line that contains 3 numbers, d (d ∈ {00, 10, 20, 30, 40, 50, 60, 70, 80, 90}), a, and b (1 ≤ a ≤ b ≤ 10^{6}).
For each test case, you must print a line "Case c: y", c being the consecutive case number, and y being the number of years between a and b (inclusive) that are in the decade given by d.
