+ * @brief Implementation of [Min Binary
+ * Heap](https://en.wikipedia.org/wiki/Binary_heap)
+ * @details
+ * A Min Binary Heap is a complete binary tree-based data structure where the
+ * value of each node is less than or equal to the values of its children. This
+ * property ensures that the minimum element is always at the root, allowing
+ * efficient retrieval and removal of the smallest element.
