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

Q1. What is box model?
Ans. 
The box model is a concept in CSS that describes how elements are rendered on a web page.
• The box model consists of four components: content, padding, border, and margin.

• The content refers to the actual content of the element, such as text or images.

• The padding is the space between the content and the border.

• The border is a line that surrounds the content and padding.

• The margin is the space outside the border, separatin...read more

Q2. Difference between let and var?
Ans. 
let and var are both used to declare variables in JavaScript, but they have some key differences.
• let is block-scoped, while var is function-scoped

• let variables are not hoisted, while var variables are hoisted

• let variables can be reassigned, while var variables can be redeclared

• let variables have temporal dead zone, while var variables do not

Q3. What is map, reduce and filter?
Ans. 
map, reduce, and filter are higher-order functions in JavaScript used to manipulate arrays.
• map: creates a new array by applying a function to each element of the original array

• reduce: applies a function to an accumulator and each element in the array, reducing it to a single value

• filter: creates a new array with all elements that pass a test implemented by a provided function
