A bit of a Friday challenge...
Is it possible to compare to sequences such that items in the sequence
are consumed after the comparison?
For example, I want to compare two words to see if one is a subset of the other.
"farmer" and "frame"
If you do:
string-to-codepoints('farmer')[not(. = string-to-codepoints('frame'))]
the result is empty because the two r's in farmer are both being
compared to the single r in frame.
Currently I've a got a recursive function that removes each letter
after a match, but I'm wondering if there's a one-liner or some other
set based approach?
thanks
