# Data Structures & Algorithms Learning Repository 🚀
Welcome to my DSA learning journey! This repository serves as a comprehensive guide for learning, practicing, and revising Data Structures and Algorithms in C++.
## Repository Structure 📂
```
dsa/
├── basics/ # C++ fundamentals and basic concepts
├── data-structures/ # DS implementations and theory
├── algorithms/ # Algorithm implementations and concepts
├── techniques/ # Problem-solving patterns and approaches
├── leetcode/ # LeetCode solutions and notes
└── practice/ # Additional practice problems
```
## Solution Documentation Structure 📝
Each problem solution should include:
### 1. Problem Documentation (`problem.md`)
```markdown
# Problem Name
## Description
[Problem description]
## Constraints
- Time Limit: O(?)
- Space Limit: O(?)
- Input Constraints
## Examples
[Input/Output examples]
```
### 2. Visual Documentation (`diagrams/`)
- Use `.drawio` files for diagrams (VS Code Draw.io Integration)
- Include both source `.drawio` and exported `.png` files
- Naming convention: `approach1-flow.drawio`, `memory-layout.drawio`
### 3. Pseudocode (`pseudocode.md`)
```markdown
# Approach 1: [Name]
## High-level Idea
[Brief explanation]
## Pseudocode
```algorithm
function solve(input):
// Step 1: Initialize
...
// Step 2: Process
...
// Step 3: Return result
return result
```
### 4. Implementation (`solution.cpp`)
```cpp
/**
* Solution for: [Problem Name]
* Approach: [Approach Name]
*
* Time: O(?)
* Space: O(?)
*/
class Solution {
// Implementation
};
```
## Example Problem Structure
```
problem-name/
├── problem.md # Problem description
├── diagrams/
│ ├── approach1.drawio # Draw.io source file
│ └── approach1.png # Exported diagram
├── pseudocode.md # Algorithm steps
├── solution.cpp # Implementation
└── README.md # Solution explanation
```
## Setting Up VS Code for Diagrams 🎨
1. Install Draw.io Integration:
- Open VS Code
- Go to Extensions (Ctrl+Shift+X)
- Search for "Draw.io Integration"
- Install the extension
2. Creating Diagrams:
- Create a new file with `.drawio` extension
- VS Code will open the Draw.io editor
- Create your diagram
- Export as PNG if needed
3. Recommended Diagram Types:
- Flow diagrams
- Memory layouts
- Tree/Graph visualizations
- State transitions
- Algorithm steps
## Best Practices for Documentation 📚
1. **Problem Analysis**
- Break down the problem
- List edge cases
- Draw initial examples
2. **Visual Documentation**
- Use consistent colors/shapes
- Label important components
- Show step-by-step flow
3. **Pseudocode**
- Use clear naming
- Include comments
- Show complexity analysis
4. **Implementation**
- Match pseudocode structure
- Add detailed comments
- Include test cases
