public static long 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.ArithmeticException - if the result is too large to be represented by a long.
