Regex to Match D or E followed by 2-3 digits

Question

I've been looking for a regex to match a string that either starts with a D or an E followed 2 or 3 digits. I'm pretty terrible at writing regex but this is what I tried: ^[DE]{1}[0-9]{1,2}$

Thank you

Answer 1

starts with D or an E followed by 2 or 3 digits

You're close. Try this regex:

^[DE][0-9]{2,3}$

You don't need {1} as that is by default true and digits should be {2,3} instead of {1,2}
