Zzuli OJ 1083: Numerical statistics (multi-instance testing)

Description

Counts the number of negative, 0, and positive numbers in a given n number

Input

There are several groups of input data, one row per group, the first number of each row is an integer n (n<100), the number of values that need to be counted, and then n real numbers, and if n=0, that line is not processed.

Output

For each set of input data, the output line, a, B, and C, respectively, indicates the number of negative, 0, and positive numbers in the given data.
