Binary Heap Algorithms What is a Binary Heap? âComplete BTs (again) We discussed an array implementation for a complete Binary Tree: â¢ Put the nodes in an array, in the order in which they would be added to a complete Binary Tree. â¢ No pointers/arrows/indices are required. â¢ We store only the array of data items and the number of nodes.
