Test, validate and match regular expressions
This regular expression matches bicycle frame sizes, including combined size ranges (e.g., XXS/XS, S/M), standard single sizes (XXS through XXL), numeric sizes with one decimal place (e.g., 54.5), whole number sizes (e.g., 54), and the keyword 'youth'. It is useful for validating user input in bike size selection forms, ensuring only accepted size formats are submitted.
