Task 1

Complete the function (scramble str1 str2) that returns true if a portion of str1 characters can be rearranged to match str2, otherwise returns false.

Notes:

Only lower case letters will be used (a-z). No punctuation or digits will be included. Performance needs to be considered

Examples:

(scramble? “rekqodlw” ”world') ==> true

(scramble? “cedewaraaossoqqyt” ”codewars”) ==> true

(scramble? “katas” “steak”) ==> false

Task 2

Create a web service that accepts two strings in a request and applies function scramble? from previous task to them.

Task 3

Create a UI in ClojureScript with two inputs for strings and a scramble button. When the button is fired it should call the API from previous task and display a result.

Notes

Please pay attention to tests, code readability and error cases.
