Write a C program to sort a stack in ascending order. You should not
make any assumptions about how the stack is implemented. The following
are the only
functions that should be used to write this program:
Push | Pop | Top | IsEmpty | IsFull
The algorithm is O(N^2) and appears below.
Do we have any other better solution which is less than O(n * n) ?
void sort_stack(Stack * src, Stack * dest)
{
while (!src->IsEmpty())
{
Int tmp = src->Pop();
while(!dest->IsEmpty() && dest->Top() > tmp)
{
src->Push(dest->Pop());
}
dest->Push(tmp);
}
}
