Patch series "lib min_heap: Min heap optimizations". The purpose of this patch series is to enhance the existing min heap implementation. The optimization focuses on both the heap construction process and the number of comparisons made during the heapify operation. This patch (of 2): Improve the heap construction process by reducing unnecessary heapify operations. Specifically, adjust the starting condition from n / 2 to n / 2 - 1 in the loop that iterates over all non-leaf elements.
