HackerRank Preparation Kit Solutions

This repository contains my solutions for the 1 Month Preparation Kit on HackerRank. The challenges are organized by difficulty: Basic, Intermediate, and Advanced. Each folder includes the code solution and an explanation of the approach used.

Structure

• basic/: Challenges focusing on fundamental programming concepts and algorithms.
• intermediate/: Challenges involving complex data structures and algorithms.
• advanced/: Challenges covering advanced topics such as dynamic programming and optimization.
• mock-tests/: Mock tests for each week's progress.

Getting Started

Each challenge is in its own folder with the following structure:

• solution.ts: The code implementation of the solution.
• README.md: A brief explanation of the problem, the approach used, and complexity analysis.
