Extension Lambdas (#1)

Define the following functions so they behave the same as their standard library counterparts:

• createString() behaves like buildString(). Start by creating a new instance of StringBuilder, call the extension lambda argument on it, then return the String result.

• createList() behaves like buildList(). This function has one generic parameter. Create an ArrayList<T>, call the extension lambda argument on it, and return a read-only List.

• createMap() behaves like buildMap(). This function has two generic parameters. Create a HashMap<K, V>, call the extension lambda argument on it, and return a read-only Map.

The code in main() tests your functions against the standard library versions. Notice that buildList() and buildMap() infer their generic parameters.
