I am working on below challenge.

Given an array of non-empty strings, return a Map<String, String> with a key for every different first character seen, with the value of all the strings starting with that character appended together in the order they appear in the array.

firstChar(["salt", "tea", "soda", "toast"]) → {"t": "teatoast", "s": "saltsoda"}
firstChar(["aa", "bb", "cc", "aAA", "cCC", "d"]) → {"d": "d", "b": "bb", "c": "cccCC", "a": "aaaAA"}
firstChar([]) → {}

i was not clear on above description. please advise
