LeetCode flashcards for spaced repetition learning
npm install lc-review
lc-review is a command-line tool designed to help you manage and review your
LeetCode problems using the SuperMemo 2 (SM2) algorithm for spaced repetition.
It processes your problem-solving logs and generates a prioritized list of
problems to review based on their due dates and frustration scores.
``bash`
npm install --global lc-review@latest
Show the next n problems to review (default: 1):
- lc-review next [n]
Example:
`bash`
lc-review next 3
Record a solved attempt (confidence range: 0.0 to 1.0):
- lc-review add
Example:
`bash`add a problem result
lc-review add 1234 0.4
The tool automatically creates and maintains a solutions.log file in your
current directory to track your problem-solving history. Each entry is recorded
in the following format:
`
date=YYYY-MM-DD problem=#### confidence=N.N [skip=true]
- date: The date you solved the problem (ISO format)
- problem: The LeetCode problem number (zero-padded to 4 digits)
- confidence: Your confidence level from 0.0 (no confidence) to 1.0 (full
confidence)
- skip: Optional flag to mark a problem as skipped in reviews
This file is used by the SM2 algorithm to calculate when you should review each
problem next.
