A heap is a tree-based data structure 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 of P is greater than or equal to the key of C.

Quiz on on heap, binary and weak heap, binomial and fibonacci heap, d ary heap, ternary heap, pairing and leftlist heap, skew heap, min and max heap.

A heap is a tree-based data structure 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 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 is called the root node.
Heaps are often used to implement priority queues, which are data structures where the highest priority element is always stored at the root. Heaps are also used in sorting algorithms, such as heapsort.
Heaps can be implemented in an array, with the parent of node i being at index i // 2 and the children of node i being at indices 2i and 2i + 1.

Heaps can be used to perform a variety of operations, including:
Insert: Insert a new element into the heap.
Extract-min: Remove the smallest element from the heap.
Decrease-key: Decrease the key of an element in the heap.
Merge: Merge two heaps into one.
