Smallest product of three numbers

Question

Hello I have recently attempted one test In that test.
The question is

The program must accept N integers as the input .The program must print the smallest value obtained by multiplying three integers among N integers as the output.

-3<=N<=1000
-1000<=Each integer<=1000

Testcases are:
5
-5 3 12 5 7
Output
-420

#My code is
N=int(input())
arr=list(map(int,input().split()))
arr.sort()
if(arr[0]<0):
print(arr[0]*arr[-2]*arr[-1]
else:
print(arr[0]*arr[1]*arr[2])

For this code only 6 testcases are passed out of 8 test cases.
could you please help me what could be the other test cases.
