Following is C like pseudo code of a function that takes a number as an argument, and uses a stack S to do processing.
void fun(int n)
{
Stack S; // Say it creates an empty stack S
while (n > 0)
{
// This line pushes the value of n%2 to stack S
push(&S, n%2);
n = n/2;
}
// Run while Stack S is not empty
while (!isEmpty(&S))
printf("%d ", pop(&S)); // pop an element from S and print it
}
What does the above function do in general?
