The assignment is to create Pascal\'s Triangle without using arrays. I have the method that produces the values for the triangle below. The method accepts an integer for the

Answer 1

public static long pascalTriangle(int r, int k)
{
    if(r == 1 || k <= 1 || k >= r) return 1L;
    return pascalTriangle(r-1, k-1) + pascalTriangle(r-1, k);
}

This method allows you to find the kth value of rth row.
