I was trying to understand the question and tried a simple testcase: (3, 5), the OJ output is true. number pool is [1, 2, 3],
1st chose 1, 2nd player choose 2/3, 1st player lose;
1st chose 2, 2nd player chose 3, 1st player lose;
1st chose 3, 2nd player chose 2, 1st player lose;
how could the first player win?
1st choose 1:
If other choose 2, 1st choose 3 and wins.
If other choose 3, 1st choose 2 and wins.
