Exercise 8-3 rotate the array to the right (20 points)

int ArrayShift( int a[], int n, int m )
{
    
    int i;
    m=m%n;
    int temp[n];
    for (i=0;i<m;i++) {
    
        temp[i]=a[n-m+i];
    }
    for (i=n-1;i>=m;i--) {
    
        a[i]=a[i-m];
    }
    for (i=0;i<m;i++) {
    
        a[i]=temp[i];
    }
}
