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.

Q1. 
Path Queries Problem Statement
Consider a weighted, undirected graph with 'V' vertices numbered from 1 to 'V' and 'E' bidirectional edges. You are tasked with handling 'Q' queries. For each query, you are...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 Algorithm Problem Statement
Your task is to sort a sequence of numbers stored in the array ‘ARR’ in non-descending order using the Merge Sort algorithm.
Explanation:
Merge Sort is a divide-an...read more
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

Rat in a Maze: All Paths Problem
You are provided with an N * N maze where a rat is positioned at starting cell MAZE[0][0]. The goal is to determine and print all possible paths that the rat can take to r...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

Q1. Coding assessment of distance
Ans. 
Calculate the distance between two points in a 2D plane.
• Use the distance formula: sqrt((x2 - x1)^2 + (y2 - y1)^2)

• Ensure input validation for coordinates

• Consider edge cases like points being the same or on the same axis

Q2. Code assess of measure
Ans. 
Code assessment measures the ability of a software developer to write efficient and effective code.
• Code quality and readability are important factors in code assessment.

• Efficiency and performance of the code are also key aspects to consider.

• Ability to solve complex problems and think critically is evaluated through code assessment.

• Knowledge of programming languages, algorithms, and data structures is tested in code ass...read more
