My issue

cook your dish here

T = int(input())
while T:
N = int(input())
A = list(map(int,input().split()))
arr =
for i in list(set(A)):
s = i*(len(A)-A.count(i))
arr.append(s)
print(min(arr))
T = T - 1

My code

# cook your dish here
T = int(input())
while T:
    N = int(input())
    A = list(map(int,input().split()))
    arr = []
    for i in list(set(A)):
        s = i*(len(A)-A.count(i))
        arr.append(s)
    print(min(arr))
    T = T - 1
