Java Solutions

Shuffle an Array

• Description: Implemented a custom method to shuffle an array of numbers [1, 2, 3, 4, 5, 6, 7] without using built-in methods like Collections.shuffle().

• Implementation: The shuffleArray() method uses a random swap algorithm to shuffle the array.

---

Convert Roman Numerals to Integer

• Description: Created a function that converts Roman numeral strings (e.g., IX) into their corresponding integer values (e.g., 9).

• Implementation: The conversion is done using a dictionary of Roman numeral values and iterating over the string.

---

Pangram Checker

• Description: A function that checks if a sentence is a pangram (contains all the letters of the alphabet at least once).

• Implementation: The string is converted to lowercase and checked using a set to ensure all letters are present.

---

JavaScript Solutions

Reverse Words in a Sentence

• Description: A function that reverses each word in a sentence without changing the word order.

• Implementation: The sentence is split into words, and each word is reversed individually.

---

Sort Array in Descending Order

• Description: A custom sorting algorithm to sort an array in descending order without relying on JavaScript's built-in sort() method.

• Implementation: A simple sorting algorithm, like bubble sort, is used to sort the array in descending order.

---

HTML Projects

Basic Calculator

• Description: A simple Basic Calculator built using HTML, CSS, and JavaScript. The calculator performs basic arithmetic operations such as addition, subtraction, multiplication, and division.

• Live Demo: Basic Calculator

---

Survey Form

• Description: A Survey Form that collects user information such as Name, Date of Birth, Gender, Profession, Email, and Mobile Number. It includes form validation to ensure all fields are completed before submission.

• Live Demo: Survey Form

How to Run the Code

Java:

1. Clone the repository or download the files.
2. Navigate to the Java files (ShuffleArray.java, RomanToInteger.java, PangramChecker.java).
3. Compile and run the Java files in your IDE or terminal.

JavaScript (Node.js):

1. Clone the repository or download the files.
2. Ensure Node.js is installed. You can download it from here.
3. Open a terminal and navigate to the JavaScript files (reverseWords.js, sortArray.js).
4. Run the JavaScript files using Node.js:

   node reverseWords.js
   node sortArray.js

HTML:

1. Open basicCalculator.html or surveyForm.html in any modern web browser to interact with the projects.
2. Both projects are functional with embedded JavaScript for interactivity.
