Hello, Question for Option 1:
public static double compute(double base, Function<Integer, Integer > func){
return func.apply((int)base); }
What is the data type returned? Isn't it a double as per method name? Thanks.

Yes, it is always allowed to return an int whenever a double is expected. int will be widened to a double automatically.
