A Python-based tool that generates an optimized 125-day study plan covering all 250 NeetCode problems for coding interview preparation.

• Complete Coverage: Includes all 250 NeetCode problems with no gaps
• Personalized Start Date: Choose when to begin your study journey
• Intelligent Scheduling: 2 problems per day from the same category when possible
• Spaced Repetition: Categories cycle with intelligent spacing to optimize retention
• Progressive Difficulty: Early days focus on Easy problems, gradually increasing complexity
• Category Focus: Daily concentration on single topics for deeper pattern recognition
• Smart Timing: Easier categories appear earlier, advanced topics later in the plan

The generated plan includes:

• 125 days of structured learning
• 18 problem categories covering all major algorithmic concepts
• Difficulty progression from Easy → Medium → Hard
• Checkboxes for tracking progress
• Direct links to LeetCode problems

• Arrays & Hashing
• Two Pointers
• Sliding Window
• Stack
• Binary Search
• Linked List
• Trees
• Heap / Priority Queue
• Backtracking
• Tries
• Graphs
• Advanced Graphs
• 1-D Dynamic Programming
• 2-D Dynamic Programming
• Greedy
• Intervals
• Math & Geometry
• Bit Manipulation

python3 generate_study_plan.py

The script will prompt you to choose when to start your study plan:

• Specific date: Enter 2025年01月01日 or any YYYY-MM-DD format
• Start today: Enter today
• Start next Monday: Enter monday or just press Enter for default
• Interactive examples: The script provides helpful examples and validation

This creates NeetCode_250_Study_Plan.md with your personalized study schedule.

• generate_study_plan.py - Main generator script
• neetcode_250_complete.json - Master dataset with all 250 problems
• NeetCode_250_Study_Plan.md - Generated study plan
• CLAUDE.md - Technical documentation

• Categories weighted by difficulty and day progression
• Spaced repetition with 6-day penalty for recently used categories
• Preference for categories with 2+ available problems

• Days 1-30: Mostly Easy problems with some Medium
• Days 31-80: Mixed Easy/Medium with some Hard
• Days 81-125: Emphasis on Medium/Hard problems

• Verification that all 250 problems are included
• Statistics on category focus and difficulty distribution
• Analysis of plan effectiveness across different phases

## Day 1 - 2025年07月07日
**Topic:** Backtracking
**Problems:**
- [ ] 🟢 [Sum of All Subsets XOR Total](https://leetcode.com/problems/sum-of-all-subset-xor-totals) - *Backtracking*
- [ ] 🟡 [Subsets](https://leetcode.com/problems/subsets/) - *Backtracking*

1. Focus on Categories: Both daily problems are from the same category to build pattern recognition
2. Progressive Learning: Start with fundamentals, advance to complex algorithms
3. Spaced Review: Categories return at optimal intervals for memory retention
4. Consistent Practice: 2 problems daily maintains steady progress without burnout

• Complete problems in order for optimal learning progression
• Focus on understanding patterns within each category
• Use checkboxes to track your progress
• Review previous category problems if you're struggling with new ones
• Aim for consistency rather than speed

• Uses random.seed(42) for reproducible plan generation
• Python 3.6+ required
• No external dependencies beyond standard library
• Generates markdown with checkbox format for easy tracking

Feel free to:

• Report issues with problem categorization
• Suggest improvements to the scheduling algorithm
• Add new features or optimizations
• Share your success stories!
