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!

10010₂ = 18₁₀
56₈ = 46₁₀
А₁₆ = 10₁₀
Объяснение:
10010₂ = 1 * 2⁴ + 0 * 2³ + 0 * 2² + 1 * 2¹ + 0 * 2⁰ = 1 * 16 + 0 * 8 + 0 * 4 + 1 * 2 + 0 * 1 = 16 + 0 + 0 + 2 + 0 = 18₁₀
56₈ = 5 * 8¹ + 6 * 8⁰ = 5 * 8 + 6 * 1 = 40 + 6 = 46₁₀
А₁₆ = А * 16⁰ = 10 * 1 = 10₁₀
В качестве цифр шестнадцатеричной системы счисления используются цифры от 0 до 9 и латинские буквы от A до F.
A = 10₁₀ B = 11₁₀ C = 12₁₀ D = 13₁₀ E = 14₁₀ F = 15₁₀
