Q1. 
Shortest Path in an Unweighted Graph
The city of Ninjaland is represented as an unweighted graph with houses and roads. There are 'N' houses numbered 1 to 'N', connected by 'M' bidirectional roads. A road...read more
Ans. BFS
• Store all the edges in the form of an adjacency list ADJ. if ADJ[X][j] = Y which means there is an edge from X to Y.
• Declare a queue Q and push S in it and also declare two vectors VISITED and DISTANCE which will store whether a house is visited or not and what is a distance of the house from house S respectively.
• We will also store the PARENT, that store the node from which we will reach the current node. It will hel...read more

Q2. 
Dijkstra's Shortest Path Problem
Given an undirected graph with ‘V’ vertices (labeled 0, 1, ... , V-1) and ‘E’ edges, where each edge has a weight representing the distance between two connected nodes (X,...read more
Ans. Using Adjacency Matrix
The idea is to maintain two arrays, one stores the visited nodes, and the other array stores the distance (element at index ‘i’ denotes the distance from node 0 to node ‘i’). We pick an unvisited minimum distance vertex, then update the distance of all its adjacent vertices considering the path from source to an adjacent vertex to pass through the picked minimum distance vertex. Repeat the process...read more
