HackerEarth Color the boxes problem solution

In this HackerEarth Color the boxes problem solution you are given N boxes that are kept in a straight line. You are also given M colors such that (). You cannot change the position of boxes. Determine the number of ways to color the boxes such that if you select any M consecutive boxes then the color of each box is unique. Since the number could be large, print the answer modulo 10 to power 9 plus 7.

for(long long i=1;i<=m;i++)
{
    ans=(ans*i)%(1000000000+7);
}
cout<<ans<<endl;
