#include <stdlib.h>
/* Arrange the N elements of ARRAY in random order.
Only effective if N is much smaller than RAND_MAX;
if this may not be the case, use a better random
number generator. */
void shuffle(int *array, size_t n)
{
if (n > 1)
{
size_t i;
for (i = 0; i < n - 1; i++)
{
size_t j = i + rand() / (RAND_MAX / (n - i) + 1);
int t = array[j];
array[j] = array[i];
array[i] = t;
