my code:

t = int(input())

i = 0

for i in range(t):

flag = False

a = input()

if a[0] == "D" and a[1] == "X":

    print("Yes")

else:

    while i<=13 :

        if a[i] == a[i+1]==a[i+2]==a[i+3]:

            flag = True

            break

        else:

            i+=1

if flag:

    print("YES")

else:

    print("NO")
