REPL!!!!
String difference
You are given two strings, a and b. We consider each letter to be unique, meaning duplicates are significant. Write a function that returns the count of letters in b which do not occur in a.
Examples
(strdiff "abc" "") ;=> {} ;; no characters in b don't occur in a
(strdiff "abc" "abc") ;=> {} ;; ditto
(strdiff "" "abc") ;=> {\a 1 \b 1 \c 1}
(strdiff "axx" "abcc") ;=> {\b 1 \c 2}
(strdiff "xxxx" "xxxxxx") ;=> {\a 2} ;; two x's in b that don't occur in aThanks to this site for the challenge idea where it is considered Hard in Python. The problem has been modified from the original.
