Problem :::

Last night, I’d been invited to a party. After dinner, the host invited us to do a lottery game and gave

each of his N guests (including me) a ticket. Each ticket was a white square piece of paper in which a

positive number (with no leading zero) were written by English digits in the center. He told us the

numbers on the tickets are distinct numbers in range 1 to N, but I was not sure due to a historical

background of his personality!

Moving an eye, I read k tickets of other guests and concluded the original numbers can’t be unique

numbers in set {1, 2, …, N}. Do you agree me?!

**Input**

Input consists of 1 <= t <= 100 datasets, coming one after another. Each datasets begins with two

numbers n and k. Thereafter, in the second line, k strings (of digits 0 to 9) comes which are the

numbers I saw in guests hands. It’s guaranteed that 1 <= K <= N <= 1000 and no string (in second line of

each dataset) has no more than 5 characters.

**Output**

For each dataset, write “Never trust him, again!” if you agree me that numbers can’t be 1 to N or “Calm

down, Dude!” if you think I might be wrong.

Sample Input

3

80 3

9 9 81

50 9

1 2 3 4 5 6 7 8 01

69 3

11 11 31

Sample Output

Calm down, Dude!

Calm down, Dude!

Never trust him, again!

Description of sample output

Consider, I may have read the 180° rotated string of a guest! It’s, digits 6 and 9 are vertically mirrored of

each‐other and 0, 1 (which were written as a short line like “|” ) and 8 are self‐mirrored. Thus, the string

81 may be originally 18, but 11 and 31 are always 11 and 31!

do u have any idea about this problem?
