A registration card number of PAT consists of 4 parts:

the 1^st letter represents the test level, namely, T for the top level, A for advance and B for basic;
the 2^nd - 4^th digits are the test site number, ranged from 101 to 999;
the 5^th - 10^th digits give the test date, in the form of yymmdd;
finally the 11^th - 13^th digits are the testee's number, ranged from 000 to 999.

Now given a set of registration card numbers and the scores of the card owners, you are supposed to output the various statistics according to the given queries.

Input Specification

Each input file contains one test case. For each case, the first line gives two positive integers $N$ ( $\le 10^4$ ) and $M$ ( $\le 100$ ), the numbers of cards and the queries, respectively.

Then $N$ lines follow, each gives a card number and the owner's score (integer in $[0, 100]$ ), separated by a space.

After the info of testees, there are $M$ lines, each gives a query in the format Type Term, where

Type being 1 means to output all the testees on a given level, in non-increasing order of their scores. The corresponding Term will be the letter which specifies the level;
Type being 2 means to output the total number of testees together with their total scores in a given site. The corresponding Term will then be the site number;
Type being 3 means to output the total number of testees of every site for a given test date. The corresponding Term will then be the date, given in the same format as in the registration card.

Output Specification

For each query, first print in a line Case #: input, where # is the index of the query case, starting from 1; and input is a copy of the corresponding input query. Then output as requested:

for a type 1 query, the output format is the same as in input, that is, CardNumber Score. If there is a tie of the scores, output in increasing alphabetical order of their card numbers (uniqueness of the card numbers is guaranteed);
for a type 2 query, output in the format Nt Ns where Nt is the total number of testees and Ns is their total score;
for a type 3 query, output in the format Site Nt where Site is the site number and Nt is the total number of testees at Site. The output must be in non-increasing order of Nt's, or in increasing order of site numbers if there is a tie of Nt.

If the result of a query is empty, simply print NA.
