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?
