Subject: lib min_heap: rename min_heapify() to min_heap_sift_down()
Date: Fri, 24 May 2024 23:29:54 +0800
After adding min_heap_sift_up(), the naming convention has been adjusted
to maintain consistency with the min_heap_sift_up(). Consequently,
min_heapify() has been renamed to min_heap_sift_down().
