C :

int main(int argc, char* argv[])
{
	int n,m,num[100],i;
	while(~scanf("%d",&n))
	{
	   for(i=0;i<n;i++)
		   scanf("%d",&num[i]);
	   scanf("%d",&m);
	   for(i=n-m;i<n;i++)
		   printf("%d ",num[i]);
	   for(i=0;i<n-m;i++)
           printf("%d ",num[i]);  
	}
	return 0;
}

C++ :

#include <iostream>
using namespace std;
int main ()
{
    int n,m;
    int num[500];
    cin>>n;
    for (int i = 0;i < n; i++)
        cin>>num[i];
    cin>>m;
    if (n == m)
    {
        for (int i = 0;i < n; i++)
            cout<<num[i]<<" ";
        cout<<endl;
    }
    else
    {
        for (int i = n-m;i < n; i++)
            cout<<num[i]<<" ";
        for (int i = 0;i < n-m; i++)
            cout<<num[i]<<" ";
        cout<<endl;
    }
    return 0;
