3.We are trying to find the correct path in a maze. We start at the entrance. At some points, we have to choose a direction to explore. If we reach a dead end, we come back to the most recent intersection where we still have an unexplored direction to investigate. What is a good data structure to keep track of the intersections we have visited?

Which of the following graphs satisfies the below properties:
1. $∣ V C (G) ∣$ = $3$ , where $V C (G)$ is the minimum vertex cover of a graph $G .$
2. $∣ PM (G) ∣$ = $3$ , where $PM (G)$ is the perfect matching of a graph $G .$

7.Which of the following statements is(are) true?

BFS can be used to identify the vertex which is at the farthest distance from $v$ in any graph, in terms of number of edges, where vertex $v$ is the starting vertex.

BFS and DFS identifies all the vertices reachable from the starting vertex $v .$

BFS cannot be used to check for cycles in the graph while DFS can be used to check for cycles in the graph.

DFS can be used to identify the shortest distance from starting vertex $v$ to every other vertex in the graph, in terms of number of edges.

A company manufactures $10$ chemicals $x_{1}, x_{2}, x_{3}, \dots. x_{10} .$ Certain pairs of these chemicals are incompatible and would cause explosions if brought into contact with each other. Below graph shows the incompatibility of the chemicals, each vertex represents the chemical and each edge between a pair of chemicals represents that those two chemicals are incompatible. As a precautionary measure the company wishes to partition its warehouse into compartments, and store incompatible chemicals in different compartments. What is the least number of compartments into which the warehouse should be partitioned?

10. An incomplete undirected graph is given below and the numbering on each vertex denotes the colouring of the graph(‘ $1$ ‘ denotes color 1, ‘ $2$ ’ denotes color $2$ , and ‘ $3$ ’ denotes color $3$ ). Find the number of maximum edges that can be added to the given graph such that the colouring is retained and the graph is planar.
NOTE: Planar graph is a graph that can be drawn on the plane in such a way that its edges intersect only at their endpoints.

Answer –6
