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!

V = 32 000 байтов
X * Y = 320 * 400 — размер изображения
Найти: N
1) V = x * y * i
2) N = 2i
Нам неизвестно i, выразим его из первой формулы
Переведем 32 000 байтов в биты = 32 000 * 8 = 256 000 бит
256 000 = 320 * 400i
256 000 = 128 000i, отсюда =>
i = 256 000 : 128 000 = 2
3) N = 22= 4
