1.1② Sports meeting score statistics
[Problem description]
The n schools participating in the sports meeting are numbered 1~n. The competition is divided into m men's events and w women's events, and the event numbers are 1~m and m+1~m+w respectively. Due to the large difference in the number of participants in each project, some projects only take the top five, and the scoring order is 7, 5, 3, 2, 1; some projects only take the top three, and the scoring order is 5; 3, 2. Write a statistical program to generate various transcripts and score reports.
[Basic requirements]
Generate transcripts for each school, including the project number, ranking (score), name and score of each achievement obtained by each school; generate a team total score report, including the school number, total score of the men's team, Women's team total score and overall team score.
[Test data]
For n=4, m=3, w=2, the top five items with odd numbers are selected, and the top three items with even numbers are selected. Design a set of example data.
[Implementation Tips]
You can assume that n≤20, m≤30, w≤20, and the name length does not exceed 20 characters. At the end of each event, enter its number and type (differentiate between the top five or the top three), and enter the athlete's name, school name (and results) in order of ranking.
[Selected Content]
Allows users to specify other ranking methods for a certain project.
Without further ado, let’s get straight to the code! (Private messages and comments welcome!)
