Regular Expression - Two Digit Range (23-79)?

Question

I have been reading the regex questions on this site but my issue seems to be a bit different. I need to match a 2 digit number, such as 23 through 75. I am doing this on an H

Answer 1

If I want 2 digit range 0-63

/^[0-9]|[0-5][0-9]|6[0-3]$/

1. [0-9] will allow single digit from 0 to 9
   
2. [0-5][0-9] will allow from 00 to 59
   
3. 6[0-3] will allow from 60 till 63

This way you can take Regular Expression for any Two Digit Range
