A linked list has a cycle such that if you start at any node p and follow a sufficient number of subsequent links, you will end up at node p. Not that p does not have to be the list's initial node. Assume you are given an N-node linked list. The value of N, on the other hand, remains unknown. 1. Create an O(N) algorithm to check if a list includes a cycle. You may add O(N) more spaces. 2. Rep the previous question, this time using just O(1) more space. (Hint: Use two pointers that start at the beginning of the list but progress at separate rates.)

Mark Zuckerberg, the CEO of Facebook, has hired you to lead the Facebook Algorithms Group. He has asked you to use various graph algorithms to analyze the world's largest social network. The Facebook Graph has 2.8 billion vertices, with each vertex being a Facebook user. Two vertices are connected provided those two users are "friends". The first decision you need to make is how you want to model the Facebook graph. Determine whether you should use an adjacency-list representation or an adjacency-matrix representation.
Wouldyou use the adjacency list structure or the adjacency matrix Strijc each of the following cases? Justify your choice. a. The graph has 10,000 vertices and 20,000 edges, and it is importan as little space as possible. b; The graph has 10,000 vertices and 20,000,000 edges, and it is impo use as little space as possible. c. You need to answer the query arëAdjacent as fast as possible, no how much space you use.

Build the d table for the following graph if you use the breadth first search and start from node s. Remember that we use the alphabetical order rule Assume the blanks/boxes are for the following nodes. Each blank/box is for one node. starting from node r followed by s, t, u, v, w, x, and y, respectively. S t и V W y
Your second function is called “isTree". Its input is a graph G, which is a dictionary whose keys are the vertices, and whose values are lists of vertices that are adjacent to the given vertex. Its output is True if G is a tree and False if G is not a tree. Hint: You may want to make use of your "connected" function from the last coding assignment.

Answer:
Write to code describes how to create the links dataset that represents the input graph. In this particular case, the links represent a directed network. The links dataset has only the nodes identification, which means, the from and to variables. The link weights in the transitive closure problem are irrelevant. In other words, it doesn’t matter the cost or the weight of the links, the algorithm searches for the possible paths to connect the nodes within the input graph. If there is a link or a set of links, no matter the weights, that connects node i to node j, that is the matter.
