Each item in this list points to the spiral's intersection with the code starting from 'p'.

1. p      -> The variable p
2. *      -> is a pointer to a value
3. size_t -> of type size_t.
4. *      -> Indirection operator. Indicates that although we've gone through all this trouble to make p a (size_t *), that we actually want to look at the memory address pointed to by p.
