### Instructions
|
|
|
|
|
|
|
|
|
|
Write a program that takes two `string` and displays, without doubles, the characters that appear in either one of the `string`.
|
|
|
|
|
|
|
|
|
|
The display will be in the order characters appear in the command line, and will be followed by a newline (`'\n'`).
|
|
|
|
|
|
|
|
|
|
If the number of arguments is different from 2, then the program displays newline (`'\n'`).
