Can heaps have duplicate values
WebNov 21, 2024 · Can heaps have duplicate values? First, we can always have duplicate values in a heap — there’s no restriction against that. Second, a heap doesn’t follow the rules of a binary search tree; unlike binary search trees, the left node does not have to be smaller than the right node!

In computer science, a heap is a specialized tree-based data structure which is essentially an almost complete tree that satisfies the heap property: in a max heap, for any given node C, if P is a parent node of C, then the key (the value) of P is greater than or equal to the key of C. In a min heap, the key of P is less than or equal to the key of C. The node at the "top" of the heap (with no paren… May 8, 2010 ·
