What does this regex mean (0+1)*?

Question

I have this reggae (0+1)* and it is said that this is array of 0 and 1. * means "zero or more".

My question is what is exactly 0+1? Is it 01010101010 or random 0 and 1?

you said yourself, `* means "zero or more"`. By the same rules, `+` is "one or more". — keltar, Jan 30 '15 at 12:41

This regex means that you can zero or more occurrences of group 0+1.

And group 0+1 means: one or more occurrences of 0 followed by 1.

Examples:
