It had some coding questions related to graph.

Q1. Dijkstra's shortest path
You have been given an undirected graph of ‘V’ vertices (labelled from 0 to V-1) and ‘E’ edges. Each edge connecting two nodes u and v has a weight denoting the distance between th...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. Check If Path Exists
You are given a directed and unweighted graph of 'V' vertices and 'E' edges. All edges are given in a 2-dimensional array ‘Edges’ in which ‘Edges[i][0]’ and ‘Edges[i][1...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

The round was really tough only 1 coding question was asked

Q1. Encode N-ary tree to binary tree
You have been given an N-ary tree ‘N’ nodes with node ‘1’ as head of the tree. Encode the above N-ary tree into a binary tree such that if only the encoded binary tree was ...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

Q2. Technical Questions
What are the different lifecycle methods in React?
 Explain Strict Mode in React.
How to prevent re-renders in React?
Ans. 
Lifecycle methods in React, Strict Mode, and preventing re-renders.
• Lifecycle methods in React include componentDidMount, componentDidUpdate, componentWillUnmount, etc.

• Strict Mode is a tool for highlighting potential problems in React components.

• To prevent re-renders in React, use shouldComponentUpdate or React.memo.
