Instructions

Write a program that prints the corresponding letter in the n position of the latin alphabet, where n is each argument received.

For example 1 matches a, 2 matches b, etc. If n does not match a valid position of the alphabet or if the argument is not an integer, the program should print a space (" ").

A flag --upper should be implemented. When used the program prints the result in upper case. The flag will always be the first argument.
