Algorithm to find Level of each node from root node

In this article we will be discussing on how to find the level of each node in a graph, the algorithm that we will be using to find the level of each node is breadth first search so if you are not familiar with breadth first search , I would suggest you to first go through this article:

Read about Breadth First Search (BFS)

then get back to this for better comprehension.

The above diagram summarises how breadth first search takes place in graph.
