## HackerRank Matching Zero Or More Repetitions Solution

*
The * tool will match zero or more repetitions of character/character class/group.

For Example:

w* : It will match the character `w` 0 or more times.
[xyz]* : It will match the characters `x`, `y` or `z` 0 or more times.

• S should end with 0 or more `uppercase letters`

Note

This is a regex only challenge. You are not required to write any code.
You have to fill the regex pattern in the blank (`_________`).
