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 ___.
