wordmultiple challenge

Hi,

I am working on below challenge




wordMultiple

Given an array of strings, return a Map<String, Boolean> where each different string is a key and its value is true if that string appears 2 or more times in the array.

wordMultiple(["a", "b", "a", "c", "b"]) → {"b": true, "c": false, "a": true}
wordMultiple(["c", "b", "a"]) → {"b": false, "c": false, "a": false}
wordMultiple(["c", "c", "c", "c"]) → {"c": true}

do i need to care about the output sorting of values like alphabetical ascending or descending etc.

please advise
