YAPP  Yet Another Permutations Problem
How many permutations of the first N numbers exist such that the maximum element between the indices [i..j] is either present at index i, or at index j ?
Input
The first line contains the number of test cases T. Each of the next T lines contains an integer N
Output
Output T lines containing the required answer for the corresponding test case. Since the answers can get really big, output the result modulo 1000000007.
Example
Sample Input: 1 2 Sample Output: 2
Constraints
1 <= T <= 10000
1 <= N <= 1000000000

Use modular exponentiation.

Anyone Help... used exponentiation... used ans=1 for n=0 and 1, tests where my code might go wrong ans for n=10 is 512... i got that...

Some sample tests where my program goes wrong... used exponentiation.... for n=0,1 ans=1 also.. even then wrong ans... Help anyone??

For those who feel the problem statement is not clear, you have to find the number of permutations such that for all i,j 1<=i<=j<=n the maximum element between the indices [i..j] is either present at index i, or at index j Last edit: 20151213 19:28:16

no need of permutation and combination

for n=0...ans is 1.

if getting TLE use modular arithmetic..
