Dice Combinations

'''Your task is to count the number of ways to construct sum n by throwing a dice one or more times. Each throw produces an outcome between 1 and  6.
For example, if n=3, there are 4 ways:

1+1+1
1+2
2+1
3

Input
The only input line has an integer n.
Output
Print the number of ways modulo 10^9+7.
