03. Student Credits - Exam Preperation
Хорица, здравейте. Задачата е доста лесна, но реших да видя дали помня нещо от RegEx и вмъкнах малко от него. Всъщност резултатите са едни и същи с това, което е в Judge, но явно нещо има с Unit Test-овете и ми дава 0/100. Ако някой има идея, да помага.

03. Student Credits
Diyan is a student and he wants your help.
He wants a program that calculates whether he gets a diploma or not.
Write a function students_credits which receives a different number of strings.
Each string will be in the format: "{course name}-{credits}-{max test points}-{diyan's points}".
Your task is to calculate the credits Diyan manages to get from all courses. The credits he gets are proportional to his points on the test. For example, if the credits of a course are 25, and Diyan achieved to get 50 of 100 max test points, he will get 12.5 credits for the course.
Also, you need to keep track of each course and Diyan's credits and sort them in descending order by Diyan's credits.
Finally, return a string on multiple lines containing:
- Diyan's achievement message:
- If the sum of all of Diyan's credits is more than or equal to 240, return: "Diyan gets a diploma with {total credits} credits."
- Otherwise, return: "Diyan needs {credits needed} credits more for a diploma."
- Information for each course and Diyan's credits:
- "{course name} - {diyan's credits}"
- Note: Each course data should be on a new line.
- All credits must be formatted to the first decimal place.
Note: Submit only the function in the judge system
Input
- There will be no input, just any number of strings with courses data passed to your function
Output
- The function should return a string in the format described above:
Constraints:
- There will always be at least one course.
- There will not be two or more courses with the same name.
- All points and all credits will be whole numbers

First, we get the data for the Computer Science course. The total credits for this course are 12, and Diyan manages to reach 250 points out of 300 total points on the test. We calculate what percentage of the test Diyan took -> 250 / 300 = 83.3%. After that, we find the credits that he has for this course -> 12 * 83.3% = 10. Next, we get the data for the Basics Algebra course. Diyan manages to get 200/400 points on the test and receives 7.5 credits. We get the data for the Algorithms course. Diyan manages to get 490/500 points on the test and receives 24.5 credits. Diyan's total credits are 42. However, it is less than 240, so he can't get a diploma. Finally, we sort the courses by Diyan's credits in descending order and return all the needed output. |
