Q1. What is api and how it is work ?
Ans. 
API stands for Application Programming Interface. It is a set of rules and protocols that allows different software applications to communicate with each other.
• APIs define the methods and data formats that applications can use to request and exchange information.

• APIs can be used to access services provided by other software applications, such as retrieving data from a database or sending notifications.

• Examples of APIs ...read more

Q2. What is software development life cycle and which steps are following?
Ans. 
Software development life cycle (SDLC) is a process used by software developers to design, develop, and test software.
• 1. Planning: Define the project scope, requirements, and objectives.

• 2. Analysis: Gather and analyze user requirements.

• 3. Design: Create a detailed design of the software.

• 4. Implementation: Develop the software based on the design.

• 5. Testing: Test the software for bugs and issues.

• 6. Deployment: Release t...read more

Q1. Difference between string and string builder.
Ans. 
String is immutable, while StringBuilder is mutable and more efficient for concatenating strings.
• String is immutable, meaning once created, its value cannot be changed. StringBuilder is mutable, allowing for modifications without creating new objects.

• String concatenation creates a new string object each time, while StringBuilder modifies the existing object directly.

• StringBuilder is more efficient for concatenating mul...read more

Q2. What is async and await
Ans. 
Async and await are keywords in JavaScript used to work with asynchronous code.
• Async is used to define a function as asynchronous, allowing it to run in the background without blocking the main thread.

• Await is used to pause the execution of an async function until a Promise is settled, and then resumes the function with the resolved value.

• Async/await is a more readable and cleaner way to write asynchronous code compare...read more

Q1. Path Queries
You are given a weighted, undirected graph with ‘V’ vertices numbered from 1 to ‘V’ and ‘E’ bidirectional edges.
You have to answer ‘Q’ queries. Every query has two integers, ‘u’, ‘v’, repre...read more
Ans. Dijkstra Algorithm
We will run Dijkstra Algorithm for all vertices in this approach and store the minimum distance in an array. Then we can answer the queries using this distance array.
 
Dijkstra Algorithm is one of the most popular algorithms in graph theory. A single-source shortest path algorithm gives the shortest path length to all vertices from a given vertex known as the source vertex. It is a greedy algorith...read more

Q2.  Merge Sort
Given a sequence of numbers ‘ARR’. Your task is to return a sorted sequence of ‘ARR’ in non-descending order with help of the merge sort algorithm.
Example :
Merge Sort Algorithm -

Ans. Recursion
The basic idea is that we divide the given ‘ARR’ into two-part call them ‘leftHalves’ and ‘rightHalves’ and call the same function again with both the parts. In the end, we will get sorted ‘leftHaves’ and sorted ‘righthalves’ which we merge both of them and return a merged sorted ‘ARR’.
We implement this approach with a divide and conquer strategy.
 
Here is the algorithm : 
 
1. Divide ‘ARR’ into two-p...read more

Q3. Rat In a Maze: All Paths
You are given a 'N' * 'N' maze with a rat placed at 'MAZE[0][0]'. Find and print all paths that rat can follow to reach its destination i.e. 'MAZE['...read more
Ans. Backtracking Approach
Initialize, all the cells of the solution matrix used to print the path matrix to 0. First, you cannot make use of the existing maze to print the solution maze as you have to distinguish b/w 1 of maze or 1 of ‘SOLUTION matrix.
 
Form a recursive function, which will follow a path and check if the path reaches the destination or not. If the path does not reach the destination then backtrack and t...read more
