My issue

explain why this code if failing on an unknown testcase

My code

t = int(input())

while t > 0:
    n = int(input())
    a = list(map(int, input().split()))
    b = list(map(int, input().split()))
    t -= 1
# Your code goes here
    ad = 0
    om = 0
    count_a = 0
    count_b = 0
    for i in range(n):
        if b[i] != 0:
            ad += 1
        else:
            if count_a < ad:
                count_a = ad
                ad = 0
        if a[i] != 0:
            om += 1
        else:
            if count_b < om:
                count_b = om
                om = 0
    ad = max(count_a, ad)
    om = max(count_b, om)
    if ad > om:
        print("Addy")
    elif ad < om:
        print("Om")
    else:
        print("Draw")
