InputThe input contains several test cases. Each test cases consists of a number N(1<=N<=100). The input is terminated by the end of file.
OutputFor each test case, you should output how many ways that all the trains can get out of the railway.
Sample Input
1
2
3
10
Sample Output
1
2
5
16796
Hint
The result will be very large, so you may not process it by 32-bit integers.
