Skill: Add Algorithm Pattern

Add a new algorithm pattern section with proper structure.

When to Use

• •Adding a new algorithmic technique (e.g., Union Find, Segment Tree)
• •Creating a new pattern category
• •Expanding the algorithms learning section

Steps

1. Create Directory Structure

mkdir -p docs/learning/algorithms/{pattern_name}/problems

2. Create the Index Page

Create docs/learning/algorithms/{pattern_name}/index.md:

# Pattern Name

Brief description of what this pattern is and when it's useful.

## When to Use This Pattern

Use this pattern when:

- Condition 1
- Condition 2
- Condition 3

## Core Approach

### Key Concepts

- **Concept 1**: Explanation
- **Concept 2**: Explanation

### Template Pattern

```python
def pattern_template(input):
    """General template for this pattern."""
    # Template code
    pass

• •Problem Name

### 3. Add to Navigation

**CRITICAL**: Update `mkdocs.yml` nav section:

```yaml
- Algorithms:
    - Overview: learning/algorithms/index.md
    # ... existing patterns ...
    - New Pattern: learning/algorithms/new_pattern/index.md  # Add here

4. Add to Algorithms Overview

Update docs/learning/algorithms/index.md to include the new pattern in the pattern reference section.

5. Create Initial Problems (Optional)

Add at least one problem to demonstrate the pattern:

# Create problem file
touch docs/learning/algorithms/{pattern_name}/problems/example_problem.md

6. Verify

make build
make serve  # Check rendering

Checklist

• • Created {pattern}/ directory with problems/ subdirectory
• • Created index.md with full template
• • Added to nav in mkdocs.yml
• • Updated algorithms overview page
• • Created at least one example problem (optional but recommended)
• • Verified build and rendering
