Your function will be passed two functions, f and g, that don't take any parameters. Your function has to call them, and return a string which indicates which function returned the larger number.
f returns the larger number, return the string f.g returns the larger number, return the string g.neither.which_is_larger(lambda: 5, lambda: 10) ➞ "g"
which_is_larger(lambda: 25, lambda: 25) ➞ "neither"
which_is_larger(lambda: 505050, lambda: 5050) ➞ "f"
This exercise is designed as an introduction to higher order functions (functions which use other functions to do their work).
