In order to encourage his military officers, Song Jiang always made a rank list after every battle. In the rank list, all 108 outlaws were ranked by the number of enemies he/she killed in the battle. The more enemies one killed, one‘s rank is higher. If two outlaws killed the same number of enemies, the one whose name is smaller in alphabet order had higher rank. Now please help Song Jiang to make the rank list and answer some queries based on the rank list.
For each test case:
The first line is an integer N (0<N<200), indicating that there are N outlaws.
Then N lines follow. Each line contains a string S and an integer K(0<K<300), meaning an outlaw‘s name and the number of enemies he/she had killed. A name consists only letters, and its length is between 1 and 50(inclusive). Every name is unique.
The next line is an integer M (0<M<200) ,indicating that there are M queries.
Then M queries follow. Each query is a line containing an outlaw‘s name.
The input ends with n = 0
Then, for each name in the query of the input, print the outlaw‘s rank. Each outlaw had a major rank and a minor rank. One‘s major rank is one plus the number of outlaws who killed more enemies than him/her did.One‘s minor rank is one plus the number of outlaws who killed the same number of enemies as he/she did but whose name is smaller in alphabet order than his/hers. For each query, if the minor rank is 1, then print the major rank only. Or else Print the major rank, blank , and then the minor rank. It‘s guaranteed that each query has an answer for it.
