Define a decorator named performance that wraps a function to return a tuple with $(1)$ the original return value of the function and $(2)$ the amount of time that it took. For example, we should be able to write:

@performance def add$($a$,$ b$)$: return a $+$ b sum$\_$result, time$\_$taken $=$ add$(1,2)$ # sum$\_$result $==3,$ time$\_$taken ~$=0$

Hint: to create a decorator named fake$\_$performance that returns a tuple with the function call result and a string, we could do the following:

import functools def fake$\_$performance$($func$)$: @functools.wraps$($func$)$ def wrapper$(*$args$,**$kwargs$)$: result $=$ func$(*$args$,**$kwargs$)$ return result, "PUT THE ELAPSED TIME HERE AS A NUMBER" return wrapper
