Prelude to Contest Scoreboard

First, start by reading the problem statement for Contest Scoreboard. For this prelude, the input format is the same as the main problem, and you will simply be reading the input and printing out a summary in the format specified.

Input

Each input line is a four-tuple: contestant number, problem number, time of submission, and result code (L).

Output

Print the number of contests in the form:

Number of contests: x

For each contest, print the number of correct and incorrect submissions as two integers on the same line separated by a space.

There should be a blank line separating each contest and a blank line separating the first contest from the initial message (and no blank line at the end).
