SUPyF Objects and Classes - 04. Exercises

Problem:
Exercises are fun … Especially when they represent a problem from your exercises.
Implement a class Exercise, which has a topic (string), a course_name (string), a judge_contest_link (string),
and problems (collection of strings).
You will receive several input lines containing information about a single exercise in the following format:
{topic} -> {course_name} -> {judge_contest_link} -> {problem1}, {problem2}. . .
You need to store every exercise in a Collection of Exercises. When you receive the command “go go go”, you end the input sequence.
You must print every exercise, in the following format:
“Exercises: {topic}
 Problems for exercises and homework for the "{course_name}" course @ SoftUni.
 Check your solutions here: {judge_contest_link}
 1. {problem1}
 2. {problem2}
 . . .”

Examples:
Input:
ObjectsAndSimpleClasses -> ProgrammingFundamentalsExtended -> https://judge.softuni.bg/Contests/439 -> Exercises, OptimizedBankingSystem, Animals, Websites, Boxes, BoxIntersection, Messages
go go go

Output:
Exercises: ObjectsAndSimpleClasses
Problems for exercises and homework for the "ProgrammingFundamentalsExtended" course @ SoftUni.
