        public static double value​(int n,
                                   int k)
        Computes de binomial coefficient. The largest value of n for which all coefficients can fit into a long is 66.
        Parameters:
        n - Size of the set.
        k - Size of the subsets to be counted.
        Returns:
        n choose k.
        Throws:
        java.lang.IllegalArgumentException - if n < 0.
        java.lang.IllegalArgumentException - if k > n.
        java.lang.IllegalArgumentException - if the result is too large to be represented by a long.
