[Tutor] Help with input/output

[Olexander]

Hello,

please could you help me with input processing for olympiad problems.
For example, what would be the code for input and output of this
problem:

Input

The input file contains several test cases. The first line of each test case contains two integers A and D separated by a single space indicating, respectively, the number of attacking and defending players involved in the play (2 <= A,D <= 11). The next line contains A integers Bi separated by single spaces, indicating the distances of the attacking players to the goal line (1 <= Bi <= 104). The next line contains D integers Cj separated by single spaces, indicating the distances of the defending players to the goal line (1 <= Cj <= 104). The end of input is indicated by A = D = 0.
Output

For each test case in the input print a line containing a single character: “Y” (uppercase) if there is an attacking player offside, and “N” (uppercase) otherwise.
Example

Input:
2 3
500 700
700 500 500
2 2
200 400
200 1000
3 4
530 510 490
480 470 50 310
0 0

Output:
N
Y
N

I also wonder how to output several integers in one line.
Thank you.
