It will also try to merge small freed blocks with neighbors in order to produce a more valuable large free block.
Free up the memory when you’re done (with free()). Suitable for data structures that grow, shrink (e.g. linked lists, trees) Heap memory persists across function calls (it’s not local to a function)
