Calculate the score of students from the NTHU OJ scoreboard based on the passed test cases in the question.
Multiple lines of score information, where each line is an answering record for a user account.
The number of questions for a contest could have more than one.
The format of each line after line 1 is given as:
Rank, User, problem1_passed_case,problem1_total_cases, problem2_passed_cases,problem2_total_cases2, ... , problemN_passed_cases,problemN_total_cases, Total Cases
1,GEC2_105071035,3,3,2,5, ...,0,1,12
The 3,3 denotes passed_cases,total_cases of problem1.
The 2,5 denotes passed_cases,total_cases of problem2, and so on.
The score of a question is calculated as the number of passed test cases divided the number of test cases within a question.
For example, the score of problem1 is 100. And the score of problem2 is 40 (=2/5*100).
The score of a student is calculated as the average of all questions.
The score for each student of the given contest with the format:
