A binary heap is a Binary Tree with the following properties: 1) Its a complete tree (All levels are completely filled except possibly the last level and the last level has all keys as left as possible). You can do following: store a hashmap inside your heap that maps your heap values to heap indexes. That is setting two of your node pointers to the same value, so you no longer have 100 unique node pointers. Additionally, a heap is a "complete tree" -- a complete tree is one in which.
