#1

from collections import Counter
for _ in range(int(input())):

 s=input()
 a=list(s)
 l=[]
 l1=[]
 flag=0
 count=1
 
 
 #print(Counter(a))
 a1=Counter(a)
 v=(max(a1))
 
 for k in a1:
        #print(a1[k])
        l1.append(a1[k])
 #print("l1",l1)
 y=max(l1)
 #print("y",y)
 l1.remove(y)
 #print("l1",l1)
 
 if len(l1)<2:
        print("Dynamic")
        flag=1
 for i in range(len(l1)-1):
    for j in range(i+1,len(l1)):
        #print(l1*,l1[j])
        #print(l1*+l1[j],y)
        if (l1*+l1[j])==y:
            print("Dynamic")
            flag=1
            break
    if flag==1:
            break
 if flag==0:
    print("Not")
