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

Q2. What is debounce and throttling?
Ans. 
Debounce and throttling are techniques used in web development to limit the number of times a function is called.
• Debounce delays the execution of a function until after a specified time period has elapsed without additional calls.

• Throttling limits the rate at which a function is called, ensuring it is not called more than once within a specified time interval.

• Debounce is useful for handling events like resizing a windo...read more

Q3. What is diff between git merge and rebase?
Ans. 
Git merge combines changes from different branches, while rebase moves the current branch to the tip of another branch.
• Merge creates a new commit with combined changes, while rebase rewrites commit history.

• Merge preserves the commit history of both branches, while rebase creates a linear history.

• Merge is non-destructive and suitable for public branches, while rebase is destructive and should be used for private branche...read more

Q4. What is diff between git fork and clone?
Ans. 
Git fork creates a copy of a repository under your GitHub account, while git clone creates a local copy of a repository.
• Fork creates a copy on GitHub, clone creates a local copy on your machine

• Forking allows you to make changes without affecting the original repository

• Cloning downloads the entire repository to your local machine

• Forking is commonly used for contributing to open source projects

Q5. What is DOM in react?
Ans. 
DOM in React stands for Document Object Model, representing the structure of a web page as a tree of objects.
• DOM in React is a virtual representation of the actual HTML elements on a web page.

• React uses a virtual DOM to improve performance by updating only the necessary components.

• Changes to the virtual DOM are compared with the real DOM, and only the differences are updated.

• This helps in minimizing the number of DOM m...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
