3852 * The algorithm works because at each stage i is uniform

3854 *
3855 * Another possibility is to generate k bits, where 2^k >= N.
3856 * If 2^k = c*N + remainder, generate the appropriate value
3857 * if a k-bit random number is less than c*N.
3858 *
3859 * For N = 17 (numbers just larger than powers of 2 are "bad"),
3860 * the amount of information is about 4.09 bits, the best
