1. Read in a graph o Your program should read in a text file that has a edjacency matrix. Some algorithms will expect a weighted graph, but one will expect a directional graph(1s and Os). You can assume the matrix will always be symmetrical, the rows and columns represent the nodes so it has to be symmectrical You will need to read in a weighted graph for some of the weighted graph algorithms in the outlab, and a (directional) boolean graph for reachability algorithms. Example: 01101 10011 10001 01000 11100 That is directional, here is weighted.. 0 9 3 0 6 9 0 04 5 300a8 04 0 0 0 65 9 0 0 Weighted graphs are always mirror images because to get from first node to second node it is always 9 no matter which way you travel. 2. Write a method that does breadth-first search (Queue). 3. Write a method that does depth-first searchrecursion ...-I said stackin class, and that's all recursion really is. but it's easier than mplementing a stack) 1. Dijkstra's Algorithrm 2. Prim's Algorithm 3. Floyd's (find all reachable paths with a directed graph start with adjacency matrix.) 4. Floyd and Warsall's (Find shortest path). 1.
