3.Shopping Spree/Exercise: Encapsulation/C# OOP

Здравейте! Имам проблем с тази задача от exercise-а на лекцията Encapsulation. В Judge - тестовете ми дава грешка на тест 4 (80/100).

Прикачвам условието и моето решение тук:

Create two classes:

Person
Product

Each person should have a name, money, and a bag of products. Each product should have a name and a cost. The name cannot be an empty string. Money cannot be a negative number.

Create a program where each command corresponds to a person buying a product. If the person can afford a product, add it to his bag. If a person doesn’t have enough money, print an appropriate message ("{personName} can't afford {productName}").

On the first two lines, you are given all people and all products. After all, purchases print every person in the order of appearance and all products that he has bought also in order of appearance. If nothing was bought, print the name of the person followed by "Nothing bought".

In case of invalid input (negative money Exception message: "Money cannot be negative") or an empty name (empty name Exception message: "Name cannot be empty") break the program with an appropriate message. See the examples below:

Examples

Input

Output

Peter=11;George=4

Bread=10;Milk=2;

Peter Bread

George Milk

Peter Milk

END

Peter bought Bread

George bought Milk

Peter can't afford Milk

Peter - Bread

George - Milk, Milk

Maria=0

Coffee=2

Maria Coffee

END

Maria can't afford Coffee

Maria - Nothing bought

John=-3

Peppers=1;Tomatoes=2;Cheese=3

John Peppers

John Tomatoes

John Cheese

END

Money cannot be negative
