      In this assignment you will perform a parallel breadth-first search (BFS) of the 4×3 Sliding Tile state space. The result of this search will be that the distance of every state in the state space from the initial configuration will be stored in an array. In C++ you can only access items in an array using an integer offset. Thus, we cannot directly map between our Sliding Tile puzzle class and an element in the depth array. Luckily, there is a 1-to-1 mapping between states in the puzzle and integers between 0 and 12!/2. We can perform this mapping using what are called “Ranking” and “Unranking” functions. A ranking function will convert a state into an integer, and an unranking function will convert an integer into the corresponding state. T

We will be running submissions through an automated tool that detects code similarity; if you copy code, you will get caught. In this section, you are asked to implement a basic BPlusTree structure as described in the textbook (pages 344-356). For simplicity, you can assume for this project: ? no duplicate keys will be inserted ? keys will implement interface Comparable 1.1 Description A B+ tree is balanced tree structure in which the index nodes direct the search and the leaf nodes contain the data entries. (1) Constraints and Properties of B+ trees: ? Keys are sorted in the nodes. ? Nodes are sorted by their keys. For Index Nodes, the B+ tree asserts that for all keys k and adjacent pointers, before(k) and after(k), it must be that: In other words, k is the key that divides the
