这是我实验和下载的测试数据（害我费了1次尝试机会和两次测试数据下载资格）。
输入：
0 0 0
1 1 1
2 2 2
10 4 6
50 50 50
-1 7 18
17 17 18
19 17 18
21 -21 20
-1 -1 -11
-1 -1 -1
输出：
w(0, 0, 0) = 1
w(1, 1, 1) = 2
w(2, 2, 2) = 4
w(10, 4, 6) = 523
w(50, 50, 50) = 1048576
w(-1, 7, 18) = 1
w(17, 17, 18) = 131072
w(19, 17, 18) = 524271
w(21, -21, 20) = 1
w(-1, -1, -11) = 1
