发帖数: 38 | 1 Design and implement a static method map that takes two arguments, a “
function” f and a list l, and returns a new list generated from applying f
to each element of l. The original list l and its elements remain unchanged.
The method would be declared as follows:
public static java.util.List map(??? f, java.util.List l)
Write code to implement the map function and clearly define what ??? should
be. | g*****g
