Basically I have a big list:
# where (n) is over a couple hundred thousand or is 1 million
def big_list(n):
return [ randrange(-n//3,n//3) for i in range(n) ]
And using a set
I must return a new list if and only if its negative value also exists.
Ex. if list = [-3,-2,-1,2,1,4]
it should return new_list = [2,1]
I must do this using set
, and I''m really lost.
