Positive and Negative Lookahead

Positive and Negative Lookahead

The solution seems to be off a bit. I am just starting to learn regex but, I think that


is more accurate with the directions. The only difference is the commas after the digits which, I think, allows for more than just 6 letters and 2 numbers.

I don’t think you need the commas here because you don’t care if there are more than 6 alphanumeric characters, only that there are at least 6. Same for 2 digits.

Look at the strings that are being tested. The strings astr1on11aut and abc123 pass even if you don’t use commas.
