1. The Data structure used in standard implementation of Breadth First Search is?
### Answer & Explanation

### Workspace

### Report Error

Answer: Option B

Explanation:

The Breadth First Search explores every node once and put that node in queue and then it takes out nodes from the queue and explores it’s neighbors.

2. The Breadth First Search traversal of a graph will result into?
### Answer & Explanation

### Workspace

### Report Error

Answer: Option B

Explanation:

The Breadth First Search will make a graph which don’t have back edges (a tree) which is known as Breadth First Tree.

3. A person wants to visit some places. He starts from a vertex and then wants to visit every place connected to this vertex and so on. What algorithm he should use?
### Answer & Explanation

### Workspace

### Report Error

Answer: Option B

Explanation:

This is the definition of the Breadth First Search. Exploring a node, then it’s neighbors and so on.

4. What can be the applications of Breadth First Search?
### Answer & Explanation

### Workspace

### Report Error

Answer: Option D

Explanation:

Breadth First Search can be applied to all of the mentioned problems. Bipartiteness of a graph means that a graph can be divided into two disjoint sets such that every edge connects a vertex in to one in.

5. When the Breadth First Search of a graph is unique?
### Answer & Explanation

### Workspace

### Report Error

Answer: Option B

Explanation:

When Every node will have one successor then the Breadth First Search is unique. In all other cases, when it will have more than one successor, it can choose any of them in arbitrary order.
