## Description

This project is a C-based heap management library designed for systems programming environments that require manual control over memory lifecycles. It provides the fundamental utilities necessary to initialize a designated region of memory and perform dynamic allocation and deallocation of memory blocks.

The library utilizes a linked-list-based tracking system to manage memory segments, employing a first-fit strategy to locate available space within the heap. To maintain memory organization and minimize fragmentation, it implements boundary-tag coalescing, which automatically merges adjacent free blocks during the reclamation process.

These capabilities support low-level memory management in resource-constrained settings, such as bare-metal systems, embedded devices, and custom kernel development. The implementation relies on direct pointer arithmetic to calculate offsets and manage metadata headers within the heap structure.
