Python pls

Create a function call possible. This function takes a set and int to find if it's possible to use elements of the set to make the same number as the int argument. it returns True or False to see if it's possible

def possible(s, num):

#This should be a recursive function

#Do not use any other function, you only need one function

#do not import any other function

1. possible( {1}, 1 ) returns True.

2. possible( {1}, 2 ) returns False.

3. possible( {1, 5, 8, -2}, 4) returns True: 1 + 5 - 2 = 4 (8 is not used).

4. possible( {1, 5, 8, -2}, 10) returns False.

5. possible({32, 7, -85, 83, -44, 87, -70, 94}, 14) returns True: 32 -85 - 44 + 87 -70 + 94 = 14 (7 and 83 are not used).

6. possible({32, 7, -85, 83, -44, 87, -70, 94}, 6) returns False:
