notes graph depicted in figure is tree and so are the ones depicted in figure (ato (efigure tree structure ( ( ( ( (ebecause of their special structure and propertiestrees occur in many different applications in computer science did knowin figure how many outdegree present in vertex representations of graphs graph is mathematical structure and finds its application in many areas of interest in which problems need to be solved using computers thusthis mathematical structure must be represented as some kind of data structures two such representations arecommonly used these are adjacent matrix adjacency list representation the choice of representation depends on the application and function to be performed on the graph adjacent matrix the adjacency matrix for graph ( ,ewith verticesis an matrix of bitssuch that iff there is an edge from vi to vj and ij if there is no such edge ij lovely professional university
