Try this test:
1
4
1 2 3 3
Your solution output 0, but must be -1
BTW, change for(i=0;i<10002;i++) to for(i=0;i<10001;i++), your arrays size only 10001
You forget about square:
1
4
1 1 1 1
Your solution output -1, but must be 1.

Can any one please help me I am getting wrong answer on the following python code:
for _ in range(int(input())):
n = int(input())
a = sorted(list(map(int,input().split())))
l,b = [],[]
for i in range(n-1,-1,-1):
if a[i] not in l:
l.append(a[i])
elif a[i] in l and a[i] not in b:
b.append(a[i])
if len(b)==2:
break
if len(b)==2:
print(b[0]*b[1])
else:
print(-1)try this case

1 2 2 2
your output: 4
actual output : -1
Whats wrong in my code?

bro they are considering square also as rectangle in this question
A square is a quadrilateral with all four angles right angles and all four sides of the same length. So a square is a special kind of rectangle , it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles.
