# Problem IClassical Counting

You have $N$ objects, each with $M$ copies. How many ways are there to take exactly $K$ of them?

Two selections of size $K$ are considered different if the $K$-tuples for those selections are different. So, for example if $N=M=K=3$ (as in the second sample input), and the $N=3$ types of objects are labeled $A$, $B$, and $C$, then the tuple $(A,B,B)$ is different than $(B,A,B)$.

## Input

The first line of input contains three integers, $N$, $M$ and $K$ respectively, subjected to $1 \leq N, M, K \leq 10^5$.

## Output

Output the number of ways. As the number of ways could be large, output them modulo $10^6 + 7$.
