Is it a very simple problem for you? Please accept it in ten minutes.

Input

This problem contains multiple test cases! Ease test case contain a n(1<=n<=10) shows the number of players,then n lines will be given. Each line will contain the name of player and the time(mm:ss) of their finish.The end of the input will be indicated by an integer value of zero.

Output

The output format is shown as sample below.

Please output the rank of all players, the output format is shown as sample below;

Output a blank line between two cases.

题目大意就是按照后面的时间排名，所用时间小的排前面，如果时间相等，按照名字的字典序排序。不会出现相同的名字。

用sort方法给它们排序好，再输出就行，注意，这里的难点是输出的时候，

排名相同的人，他们的名次必须另外用一个数来标志。

还有，输出的时候，2个输出之间有空行。
