Consider the following snippet of a C program. Assume that swap(&x, &y) exchanges the contents of x and y.

int main() { int array[] = {3, 5, 1, 4, 6, 2}; int done = 0; int i; while (done == 0) { done = 1; for (i = 0; i <= 4; i++) { if (array[i] < array[i+1]) { swap(&array[i], &array[i+1]); done = 0; } } for (i = 5; i >= 1; i--) { if (array[i] > array[i-1]) { swap(&array[i], &array[i-1]); done = 0; } } } printf("%d", array[3]); }

The output of the program is
