Consistent algorithm problem-solving practice across multiple platforms.
- Build problem-solving skill through consistent practice on Baekjoon (BOJ), LeetCode, Programmers, Codility, and SWEA.
- Organize solutions by algorithm/data-structure category so patterns are easy to review and reuse later.
Organized by algorithm type: DP · Implementation · Graph · Exhaustive Search · Samsung SW Category · Greedy · I/O · Divide & Conquer · Binary Search · Bisection · Two Pointer · Dijkstra · Kruskal · Segment Tree · Prefix Sum · Past Contests
Coding test practice problems, including a dedicated Kakao coding test archive
🟧 LeetCode
Solutions named after each problem's slug
🟨 SWEA
Samsung SW Expert Academy problems
🟪 Codility
Codility practice problems
Java · C++ · Kotlin (new solutions are written in Kotlin)
/solve <problem-url>- Detect the platform from a problem URL and scaffold a solution file in the correct directory (you write the code yourself)/push <commit-message>- Commit changed solution files and push to the remote branch
