alphamirror

Instructions

Write a program called alphamirror that takes a string as argument and displays this string after replacing each alphabetical character with the opposite alphabetical character.

The case of the letter remains unchanged, for example :

'a' becomes 'z', 'Z' becomes 'A' 'd' becomes 'w', 'M' becomes 'N'

The final result will be followed by a newline ('\n').

If the number of arguments is different from 1, the program prints a new line.

Usage

$ go run . "abc"
zyx$
$
$ go run . "My horse is Amazing." | cat -e
Nb slihv rh Znzarmt.$
$
$ go run .
