The stack allocator is a minimalistic technique designed for straightforward memory allocation and deallocation patterns. Operating as a linear memory region with stack-like behavior, this allocator is ideal for scenarios where you need a simple and efficient approach.

1. Memory Allocation:

   • The allocator utilizes a linear memory region to allocate and manage memory.
   • Memory is allocated (st_alloc) sequentially from the start of the memory region.

2. Memory Deallocation:

   • When memory is deallocated (st_free), the stack pointer is moved back, releasing the most recently allocated memory block.

• Simple memory management approach.
• Efficient allocation and deallocation patterns.
• Minimal memory fragmentation due to the linear memory layout.

• Being a stack, the allocator operates in a last-in, first-out manner. This might not be suitable for all allocation patterns.
