Why Am I Getting Up - Down Palindrome(UPDWPAL) Wrong?

general
1 
for _ in range(int(input())):
    X = int(input())
    A = list(map(int, input().split()))
    B = A[::-1]
    if A == A[::-1]:
        print('Yes')
    else:
        for i in range(X):
            if abs((A[i]) - (B[i])) != 0 and abs((A[i]) - (B[i])) != 2:
                print('No')
                break
        else:
            print('Yes')

u are not accounting for if the midpoint is between all such pair of numbers with diff 2, if its not even with one such pair, its a no

I don’t understand, are you saying the difference cannot only be 2 or 0?
