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!

считаем рёбра точек:
1 точка — 3
2 точка — 2
3 точка — 3
4 точка — 2
5 точка — 2
3+2+3+2+2=12, но все ребра мы посчитали 2 раза, поэтому делим на 2:
12:2=6

считаем рёбра точек
1 точка — 2
2 точка — 1
3 точка — 1
4 точка — 1
5 точка — 1
2+1+1+1+1=6, но одно ребро мы посчитали 2 раза, поэтому вычитаем 1
6-1=5
Ответ: первое фото 6, второе — 5
