• Solution approach explanation
• Fully commented C++ implementation

🚀 Getting Started

1. Clone the repository:

   git clone https://github.com/amangupta143/Data-Structures-and-Algorithms.git
   

2. Navigate to any solution directory:

   cd Leetcode-Solutions/Question-Name
   # or
   cd GeeksForGeeks-Solutions/Question-Name
   

3. Read the problem's README.md to understand the approach

4. Compile and run the solution:

   g++ -std=c++17 -o solution question-name.cpp
   ./solution
   

💡 LeetCode Solutions

Each LeetCode solution in the repository follows a consistent structure to help you understand the problem-solving process:

• Problem statement and constraints
• Multiple approaches (when applicable)
• Time and space complexity analysis
• Edge cases and test scenarios
• Detailed code comments explaining the implementation

🎓 GeeksForGeeks Solutions

The GeeksForGeeks solutions section contains implementations of various problems from GeeksForGeeks, featuring:

• Step-by-step problem explanations
• Multiple solution approaches where applicable
• Optimized implementations with detailed comments
