Breath First Search Distance Given a directed graph as an adjacency list, you will determine, in this challenge, the breath first search distance of all nodes from a starting vertex, s, assuming that the weight of each edge is 1. In the example graph belove, for s=0, the distances of each vertex from s are 0 1 1 2 3 The output includes the distances for the vertices, 0, 1, 2, 3, 4, in the order of the vertex number. If s=1, then the output will be -1 0 -1 1 2 For the starting vertex 1, the vertex 0 and 2 are unreachable, so the corresponding BFS distances are -1 and -1. Input Format First line in the input contains the starting vertex s Each of the subsequent lines contains two space-separated integers, v and w, that represents an edge from the node v to w. Constraints Node numbers are 0 based, i.e. if there n nodes, the nodes are numnered as 0,1,2,...,n-1. Output Format Print the distace of each vertex from the start vertex in the order of the vertex number. Sample Input 0 0 0 1 0 2…

Graph Transversal Simulation: For this graph write down the order of vertices encountered in a breadth-first search starting from vertex A. Break ties by picking the vertices in alphabetical order (for example, A before Z)
True or False: A simple path in a graph cannot be cyclic. True False
True or False: The sum of the degrees of the vertices of an undirected graph must be odd. True False
in C language implement a graph coloring method that assigns the minimum color to each vertex so it does conflict with vertices that have been colored (using adjacency list)
1. Unreachable Nodes You have been given an undirected graph consisting of N nodes and Medges. The nodes in this graph are enumerated from 1 to N. The graph can consist of self-loops as well as multiple edges. This graph consists of a special node called the head node. You need to consider this and the entry point of this graph. You need to find the number of nodes that are unreachable from this head node. Create a function unreachableNodesCount (N, M, ListofEdges, HeadNode) where N is the number of nodes, M is the number of edges, List0fEdges contains list of edges in the graph and HeadNode is a special node which is the entry point of this graph. The function will return the number of nodes that are unreachable from the head node. Note: You will need to use N, M and List of Edges to first create the graph, as well as a search function to define the unreachable nodes count. >>>N = 10 >>> M = 10 >>> ListofEdges [(8, 1), (8, 3), (7, 4), (7, 5), (2, 6), (10, 7), (2, 8), (10, 9), (2, 10),…
