### Instructions
|
||
|
|
|
||
|
|
Write a program that receives two strings and replicates the use of brackets in regular expressions. Brackets in regular expressions returns the words that contain the expression inside of it.
|
||
|
|
|
||
|
|
The program should handle the "`|`" operator, that searches for both strings on each side of the operator.
|
||
|
|
|
||
|
|
The output of the program should be the results of the regular expression by order of appearence in the string, being themselves identified by a number.
|
||
|
|
|
||
|
|
In case the regular expression is not valid, the last argument is empty or there are no matches the program returns a newline ("`\n`").
|
||
|
|
|
||
|
|
If there are more than 2 or no arguments the program should print a newline ("`\n`").
|
