# Matching {x} Repetitions – HackerRank Solution

In this post, we will solve Matching {x} Repetitions HackerRank Solution. This problem (Matching {x} Repetitions) is a part of HackerRank Regex series.

## Objective

{x}
The tool {x} will match exactly x repetitions of character/character class/groups.

For Example:

w{3} : It will match the character `w` exactly 3 times.
[xyz]{5} : It will match the string of length 5 consisting of characters {`x``y``z`}. For example it will match `xxxxx``xxxyy` and `xyxyz`.
\d{4} : It will match any digit exactly 4 times.

You have a test string S.
Your task is to write a regex that will match S using the following conditions:

• S must be of length equal to `45`.
• The first 40 characters should consist of `letters`(both lowercase and uppercase), or of `even digits`.
• The last 5 characters should consist of `odd digits` or `whitespace characters`.

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 (`_________`).
