Q1. 1.Explain OOPs concept
Ans. 
OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
• OOPs focuses on creating reusable code by organizing it into objects

• Key principles include encapsulation, inheritance, and polymorphism

• Encapsulation allows data hiding and protects data from outside interference

• Inheritance enables a new class to inherit properties and behaviors from an existing ...read more

Q2. While Loop cycle
Ans. 
A while loop is a control flow statement that allows code to be executed repeatedly based on a given condition.
• While loop continues to execute a block of code as long as the specified condition is true

• The condition is evaluated before each iteration of the loop

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

Q3. 
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
