To be considered as a flow network,  what does a graph needs to consist of? a loop edge capacity a greedy strategy a sink a pipeline a source

Draw the adjacency list for the given undirected graph. No need for any program or something.

True or false: A max flow of a graph is always the sum of a subset of its edges.

In a graph, two vertices are connected if there is a path between them. If all vertices are connected, we say the graph is connected. Given the Graph ADT below: class Graph { public: void addEdge (int vl, int v2); void delEdge (int vl, int v2); bool hasEdge (int v1, int v2) const; VList adj (int v) const; int v() const; int e() const; } ; Fill in the function isConnected that tells whether graph g is connected or not. Note that you can only use the above methods for g. You may assume vertex ID starts from 0 and define other helper functions if necessary. bool isConnected (const Graph &g) { // Copy this function in the answer and add code below this line.
