> While seemingly obsolete, there are a ton of pre-heap / pre-stack algorithms for dynamically changing arrays or other data structures. These are not as obsolete as they might seem to many. In some environments you might still be very restricted and want to avoid all dynamic allocation which could force you to use these types of algorithm so you can work in-place in a static memory block.
