WebExercise: BuildHeap. A heap can be built from a table of random keys by using a linear time bottom-up algorithm (a.k.a., Build-Heap, Fixheap, and Bottom-Up Heap Construction). This algorithm ensures that the heap-order property (the key at each node is lower than or equal to the keys at its children) is not violated in any node.

Heaps are usually implemented with an array, as follows: • Each element in the array represents a node of the heap, and • The parent / child relationship is defined implicitly by the elements' indices in the array. For a binary heap, in the array, the first index contains the root element.
