I have checked if there is any kind of worst case input, as described above, present in test data using the following code.

for test in range(int(input())):
    n = int(input())
    l = list(map(int, input().split()))
    if len(set(l)) == 1 and n >= 2 * 10**4:
        raise ValueError("Worst case input")

I got WA instead of RTE. It is clear that such input doesn’t exist in test data.
