### Instructions
|
||
|
|
|
||
|
|
Write a program that takes two strings and displays, without doubles, the
|
||
|
|
characters that appear in either one of the strings.
|
||
|
|
|
||
|
|
The display will be in the order characters appear in the command line, and
|
||
|
|
will be followed by a \n.
|
||
|
|
|
||
|
|
If the number of arguments is not 2, the program displays \n.
|
||
|
|
|
||
|
|
Example :
|
||
|
|
|
||
|
|
```console
|
||
|
|
