dsap-cli 1.0.1

CLI tool for practicing data structures and algorithms using spaced repetition.

Data Structures and Algorithms Practice (DSAP)

DSAP is a terminal-first CLI that schedules coding interview problems using the SM-2 spaced repetition algorithm,
helping you retain patterns long-term instead of forgetting them after solving once.

Why DSAP?

Most developers preparing for technical interviews solve algorithm problems once and never revisit them.

As a result, they forget patterns they previously learned.

DSAP solves this by scheduling problems using spaced repetition, a learning technique proven to improve
long-term memory.

Benefits:

• Retain algorithm patterns long-term
• Structured daily practice
• Automatic scheduling of reviews
• Focus on problems you’re about to forget

Instead of guessing what to practice next, DSAP tells you exactly what to review.

Installation

# Recommended
uv tool install dsap-cli

# Alternatives
pipx install dsap-cli
pip install dsap-cli

Verify installation:

dsap --version

---

Quick Start

# Load problems and set focus
dsap load blind75
dsap config preferred_set blind75

# Start practicing
dsap next

For the full workflow see:

USER_GUIDE.md

Example Session

$ dsap next

Next Problem
Two Sum (Easy)

Category: Arrays
Set: Blind 75

Open problem in browser? [y/N]

After solving, rate your recall:

5 - Perfect
4 - Good
3 - Hard
2 - Incorrect but remembered idea
1 - Incorrect
0 - Complete blackout

DSAP then schedules the next review automatically.

Problem Sets

Set	Problems	Description
blind75	75	Core interview essentials
neetcode150	150	Comprehensive curriculum
grind75	75	Flexible study roadmap

dsap load --list
dsap load blind75
dsap load ./custom.yaml

---

Configuration

dsap config --list
dsap config preferred_set blind75
dsap config daily_goal 5
dsap config preferred_difficulty Medium
dsap config auto_open_browser false
dsap config --reset

Setting	Default	Description
preferred_set	None	Default problem set
daily_goal	5	Target problems per day
preferred_difficulty	None	Filter by difficulty
show_hints	true	Show problem hints
auto_open_browser	true	Open problems in browser

---

How It Works

DSAP implements the SM-2 (SuperMemo 2) spaced repetition algorithm.

After solving each problem, rate your recall from 0–5.

Rating	Meaning	Effect
5	Perfect	Interval grows
4	Good	Interval grows
3	Hard	Interval grows slowly
0-2	Forgot	Interval resets

Typical interval progression:

1 day → 6 days → 15 days → 38 days → 95 days

After several successful reviews, problems reappear only every few months.
