Write a program that lets you know if you can have a key or not, based on your role at the school.
First ask for the user’s role at the school. They can be a student, administrator, or a teacher. (And remember that capitalization is important! ‘Student’ is not the same as ‘student’.)
Example 1: Administrator or Teacher
For example, if this was the input:
Are you an administrator, teacher, or student?: teacher
This should be the output:
Administrators and teachers get keys!
Example 2: Student
And if this was the input:
Are you an administrator, teacher, or student?: student
This should be the output:
Students do not get keys!
(Note: You should also be able to handle a situation where the user enters a value other than administrator, teacher or student and tell them they must be one of the three choices!)
Example 3: Other
If they input anything else:
Are you an administrator, teacher, or student?: secretary
This should be the output:
You can only be an administrator, teacher, or student!

Объяснение:
У нас 1 пиксель требует 16 бит
Всего таких пикселей 640 * 480 = 307 200 штук
Итого для передачи данных об их глубине цвета требуется передать
307 200 * 16 = 4 915 200 бит.
Модем у нас работает со скоростью 124 кбит/c,
то есть за каждую секунду он передает 124 * 1024 = 126976 бит/c
Для передачи 4 915 200 бит с такой скоростью потребуется:
4 915 200 / 126 976 = 38,7097 c, округленно 39 с.
