Jiudu OnlineJudge 1014: Ranking_PHP Tutorial

Title description:                  

Although there is a real-time Ranklist for today’s computer-based exam, the ranking above is only based on the number of questions completed, and does not take into account the score of each question, so it is not the final ranking. Given the admission score, please write a program to find the candidates who finally passed the score and print their scores in descending order.

Input:                                                  

The test input contains information from several exams. The first line of each exam information gives the number of candidates N ( 0 < N < 1000 ), the number of test questions M ( 0 < M < = 10 ), and the score line (positive integer) G; the second line sorting gives Positive integer scores from questions 1 to The question number of the question (the question number ranges from 1 to M).

When the number of candidates read in is 0, the input ends and the exam will not be processed.

Output:                                                                      

For each exam, first output the number n of candidates who are not lower than the score line in the first line, and then output the test number and score of the online candidates from high to low in the n lines, separated by 1 space. If there are multiple candidates with the same score, the results will be output in ascending order of their exam numbers.

Sample input:
