World Cup
BrasilTimelimit: 1
A Button Soccer World Cup is being held with teams from around the world. The classification is based on the number of points earned by the teams, and the distribution of points is done in the usual way. That is, when a team wins a game, it gets 3 points if the game ends in a draw, both teams get 1 point, and the loser no points.
Given the current standings of the teams and the number of participating teams in the World Cup, his task is to determine how many games ended in draws so far.
Input
The input contains several test cases. The first line of a test case contains two integers T and N, respectively indicating the number of participating teams (2 ≤ T ≤ 200) and the number of matches played (0 ≤ N ≤ 10000). Each of the next T lines contains the name of a team (a string of up to 10 letters and digits), a space, and the number of points the team got so far. The end of input is indicated by T = 0.
Output
For each test case your program must print a single line containing an integer representing the amount of games ended in draws.
