ASCII Characters

　

Inside a computer, all information is treated as numbers. For example, in the ASCII code, the uppercase letter 'A' is assigned the numeric value 65. Similarly, capital letter 'B' is assigned 66, 'C' is assigned 67, and so on. In the ASCII code, lower case 'a' is assigned 97. Similarly, lowercase 'b' is assigned 98, 'c' is assigned 99, and so on. In this way, 'a' through 'z' are consecutively assigned 97 through 122, respectively.

Write a program to determine whether a given number in ASCII code represents an uppercase or lowercase letter of the alphabet.
