Suppose a stack $S$. Which is empty initially consider the following code:
int values[] = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19};
for(int i=0; i<10; i++)
{
S.PUSH = (values[i]);
}
int n = 25;
for (int i=0; i<4; i++)
{
n+= S.POP();
}
for(int i=0; i<2; i++)
{
n-= S.POP();
}
printf("%d",n);
The output of the program code is _________ .
