1025. PAT Ranking (25)

Description: Programming Ability Test (PAT) is organized by the College of Computer Science and Technology of Zhejiang University. each test is supposed to run simultaneously in several places, and the ranklists will be merged immediately after the test. now it is your job to write a program to correctly merge all the ranklists and generate the final rank. input Specification: Each input file contains one te St case. for each case, the first line contains a positive number N (<= 100), the number of test locations. then N ranklists follow, each starts with a line containing a positive integer K (<= 300), the number of testees, and then K lines containing the registration number (a 13-digit number) and the total score of each testee. all the numbers in a line are separated by a space. output Specification: For each test case, first print in one line the total number of testees. then print the final ranklist in the following format: registration_number final_rank location_number local_rankThe locations are numbered from 1 to N. the output must be sorted in nondecreasing order of the final ranks. the testees with the same score must have the same rank, and the output must be sorted in nondecreasing ord Er of their registration numbers. sample Input: 251234567890001 951234567890005 1001234567890003 951234567890002 771234567890004 8541234567890013 651234567890011 251234567890014 85 Sample Output: 91234567890005 1 1 11234567890014 1 2 11234567890001 3 1 21234567890003 3 1 21234567890004 5 1 41234567890012 5 2 21234567890002 7 1 51234567890013 8 2 31234567890011 9 2 4 analysis :( 1) sort and merge the struct. (2) Pay attention to processing in the case of the same grade. Reference code:
