Advanced Java coding

Q1. Entire core Java arrays and strings
Ans. 
Core Java arrays and strings are fundamental data structures used for storing and manipulating data in Java programming.
• Arrays in Java are used to store multiple values of the same data type in a single variable.

• Strings in Java are objects that represent sequences of characters.

• Arrays and strings in Java are both indexed collections, with arrays being mutable and strings being immutable.

• Example: String[] names = {"Alic

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.

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 :

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
