top-down heap construction

Top-down heap construction is a method used to build a heap data structure, which is a specialized tree-based data structure. In this process, we start with an empty heap and iteratively insert elements one by one at the end of the heap. As each element is inserted, it is compared with its parent node and swapped if it violates the heap property. This process continues until the element reaches its correct position in the heap. By repeating this operation for all elements, a complete heap is constructed efficiently from top to bottom.
