| Problem D.Number Game |
Let’s play a number game. I will give you 2N-1(N=2^k, k=1,2,3,4,5,6,7,8,9,10) numbers, each number is a positive integer not bigger than 1000. Can you choose N of them, and add them all to a integer S, to make that S/N is a integer? If there are many solutions, you can only find one of them.
The input file contains several scenarios. Each of them consists of 2 lines.
For each scenario, the first line is a number N, the second line consist of 2N-1 numbers. There is a space between two numbers.
The file will be ended with N=0.
For each scenario, print a single line ‘No’ if you can’t find an answer. Otherwise print a line ‘Yes’, and then the other line containing N numbers (in any order), there should be a space between two numbers.
