Input

The first line contains an integer T, total number of testcases. Then follow T lines, each line contains an integer N.


Output
Output the given string or -1 depending on conditions.

Constraints

-20 ≤ N ≤ 20


Example

Input
3 
1
12
-5
Output
What an obedient servant you are!
-1
What an obedient servant you are!
t=int(raw_input())

a=[0 for i in range(t)]
for i in range(t):
    a[i]=(int)(raw_input())
    
re=[0 for i in range(t)]    
for i in range(0,t):
    if(a[i]<10):
        re[i]="What an obedient servant you are!"
    else:
        re[i]="-1"
for i in range(t):
    print re[i]
