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!
   
Ответ: 2025 Кбайт
Объяснение: При палитре цветов 256 глубина цвета будет 8 бит (2 в 8-й степени будет 256). Общее количество пикселей изображения будет 1920 умножить на 1080 и умножаем на 8 бит. Всё это делим на 8 (перевели в байты), затем делим на 1024 (перевели в Кбайты): (1920*1080*8)/8/1024 = 2025 Кбайт. Если поделить еще раз на 1024, то получим ответ в Мбайтах: приблизительно 2 Мбайта.
