Write the InputLessons$()$ function in the Collection class. Within InputLessons$(),$ use cin to read pairs of input, string currTopic and character currDiscount, until "completed" is read from input. Create each Lesson object with currTopic and currDiscount as arguments and append each object to vector lessonList.

Ex: If the input is Hobbies N Culture Y Fisheries Y Environment N completed, then the output is:

Lesson: Hobbies, Discount: N Lesson: Culture, Discount: Y Lesson: Fisheries, Discount: Y Lesson: Environment, Discount: N
