class Test
{
public static void countUp(int k, int n)
// displays consecutive integers from k to n
{
}
public static void countDown(int k, int n)
// displays consecutive integers backwards from k to n
{
}
public static int sum(int n)
// returns the sum of all integers 1 + 2 + .... + n-1 + n
{
}
public static int fact(int n)
// returns n factorial
{
}
public static int fibo(int n)
// returns the nth Fibonacci number
{
}
public static int gcf(int n1, int n2)
// returns the gcf of n1 and n2

80-Point and 100-Point Versions
The 100-point version requires the completion of all seven methods. The 80-point version requires only five methods. The gcf and the fibo methods are not required for the 80-point version.
