Question: Regular Expressions: Reuse Patterns Using Capture Groups

Hello, for some reason I need to have a regular expression that has two \s characters even though mine passed all the tests.


So how can I change the above so it works on all the tests and has two \s characters because ,


didn’t do it, and


solves all the tests but the one where I need two \s characters. The pattern allowed to pass are suppose to be three digits repeated with spaces between.

Nevermind. It was suppose to be /(^\d+)\s\1\s\1/.

Excuse me while I go be grumpy over here.
