1. Proves that there is a simple path between each pair of vertices of the connected undirected graph.Proof: Set U and V are two different vertices of the connected undirected graph G = (V, E), because G is connected, so there is at least one path between U and V. Set x0, x1, x2, ..., xn is the vertex sequence of the shortest path in length, where x0 = u and xn = v. This shortest path is simple. To see this, let's say it's not simple. For some I and J satisfying 0≤i 2.

introduction–mining local Blocks in Python In this guide, we'll implement a local proof-of-work mining algorithm into Python to illustrate how blocks are Network like Bitcoin. This is a continuation to the original building a simple, local, Python Blockchain–part 1. Note:a few tweaks from the "Part 1 code would be necessary to implement" the local mining functionality we desire. We won ' t be as concerned with testing the validity of the blockchain,

Prime Number and Union number For an integer a> 1, if it has only ordinary approx. 1 and A, we call a as a prime number (or prime number ). Prime numbers have many special properties and play an important role in number theory. In order, the following is a sequence of small prime numbers: , 59 ,... An integer a> 1 that is not a prime number is called a union. For example, 39 is a combination because t
