Given an ArrayList of Strings, return a new List of Strings where each element contains the first character of the same-index input String.

Precondition: every element of lst will have length > 0.

HINT

You will need a loop for this. Also remember to declare and instantiate (and return) a new ArrayList.

apcsaListFirstCharacters(["Hello", "world"]) → ["H", "w"]
apcsaListFirstCharacters(["I", "am", "legend"]) → ["I", "a", "l"]
apcsaListFirstCharacters(["Crunchy chewy", "Awesome", "Nice and sweet", "Delightful and delicious", "Yummy treat"]) → ["C", "A", "N", "D", "Y"]
