It had some coding questions related to graph.

Q1. 
Dijkstra's Shortest Path Problem Statement
You are given an undirected graph with V vertices (numbered from 0 to V-1) and E edges. Each edge connects two nodes u and v and has an associated weight represe...read more
Ans. 
The question is about finding the shortest path distance from a source node to all vertices in an undirected graph.
• The graph is represented by the number of vertices and edges, followed by the edges and their distances.

• The task is to find the shortest path distance from the source node (0) to all other nodes.

• If a node is disconnected from the source node, print the maximum positive integer value (2147483647).

• Implement ...read more

Q2. 
Path Existence in Directed Graph
Given a directed and unweighted graph characterized by vertices 'V' and edges 'E', determine if a path exists from a specified 'source' vertex to a 'destination' vertex. T...read more
Ans. 
The task is to check if there exists a path from a given source vertex to a destination vertex in a directed and unweighted graph.
• Read the number of test cases.

• For each test case, read the number of vertices and edges.

• Read the edges of the graph.

• Read the source and destination vertices.

• Implement a graph traversal algorithm (e.g., BFS or DFS) to check if a path exists from the source to the destination.

• Print 'true' if a

Q1. 
Encode N-ary Tree to Binary Tree Problem Statement
You are provided with an N-ary tree constituted of 'N' nodes, where node '1' is the head of the tree. Your task is to encode this N-ary tree into a binar...read more
Ans. 
The task is to encode an N-ary tree into a binary tree and then decode the binary tree back into the original N-ary tree.
• Encode the N-ary tree by representing each node as a binary tree node with its first child as the left child and subsequent children as the right child.

• To decode the binary tree, traverse the binary tree and for each node, create a new N-ary tree node with its left child as the first child and subseq...read more
