PAT 1153 Decode Registration Card of PAT (25)

Posted on Edited on In

A registration card number of PAT consists of 4 parts:

  • the 1st letter represents the test level, namely, T for the top level, A for advance and B for basic;
  • the 2nd - 4th digits are the test site number, ranged from 101 to 999;
  • the 5th - 10th digits give the test date, in the form of yymmdd;
  • finally the 11th - 13th 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 (≤104) and M (≤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.
