leetcode

This repository stores my LeetCode problem-solving practice in C++ and Rust.

Structure

• algorithms/: standalone C++ algorithm examples, grouped by category
  • include/: reusable data structures shared by algorithms
  • graph/: graph algorithms
  • sorting/: sorting algorithms
  • string/: string matching algorithms
  • searching/: searching algorithms
• data_structures/: standalone C++ data structure examples, grouped by category
  • tree/: binary trees, search trees, AVL trees, red-black trees, etc.
  • disjoint_set/: disjoint-set union (union-find)
• problems/: regular C++ LeetCode problems
• rust/src/bin/: regular Rust LeetCode problems managed by Cargo
• weekly_contests/: C++ weekly contest folders
• scripts/: Python helper scripts

Scripts

Install Python dependencies for chart generation:

python3 -m pip install -r requirements.txt

Create a normal C++ problem file:

python3 scripts/create_problem.py "1582. Special Positions in a Binary Matrix"

Create a normal Rust problem file:

python3 scripts/create_problem.py --lang rust "1582. Special Positions in a Binary Matrix"

Run a Rust problem locally:

cd rust
cargo run --bin p1582_special_positions_in_a_binary_matrix

Create a weekly contest folder with Q1.cpp to Q4.cpp:

python3 scripts/create_weekly_contest.py 493

Generate LeetCode statistics and charts:

python3 scripts/leetcode_stats.py

Print statistics without generating charts:

python3 scripts/leetcode_stats.py --no-plot
