The last level is filled in left-to-right until you run out of elements. So yours would start out like this: The heap invariant is that each parent is smaller than both its children. In the heap construction algorithm you work bottom up, restoring the heap invariant.

The simplest algorithmic way to remove it and find the "next" winner is to move some loser (let's say cell 30 in the diagram above) into the 0 position, and then percolate this new 0 down the tree, exchanging values, until the invariant is re-established.

Web21 de feb. de 2024 · A heap is a tree-like data structure that forms a complete tree and satisfies the heap invariant. The heap invariant states that, if A is a parent node of B, then A is ordered with respect to B for all nodes A and B in a heap. This means a parent node’s value is always greater than or equal to the value of the child nodes for all nodes in a heap.
