Introduction to the LeetCode Project by Doocs
LeetCode is a popular platform for developing and honing algorithm skills through coding challenges, and the Doocs GitHub repository enhances this experience by providing comprehensive solutions to a wide range of problems from LeetCode and other well-known algorithm collections. This project brings together solutions to problems found in "LeetCode," "Jianzhioffer (2nd Edition)," "Jianzhioffer (Advanced Edition)," and "The Programmer's Interview Classics (6th Edition)." The solutions are thoughtfully implemented in various programming languages such as Java, Python, C++, Go, TypeScript, and Rust. The goal is to cater to a wide audience by offering detailed and diverse coding practices.
Exploration and Practice
The Doocs LeetCode project site serves as a hub of resources for coders at different levels. Here, individuals can explore complete algorithm solutions for LeetCode problems, coding contests, and problems from other classical algorithm books.
Algorithm Mastery
The project delves into key algorithmic topics, which are essential for any software developer. Here are some core areas covered:
Basic Algorithms
- Binary Search: With problems like finding the first and last position of an element in a sorted array.
- Sorting Algorithms: Solutions involving Quick Sort, Merge Sort, among others.
- Prefix Sums: Problems solving range sum queries in arrays and matrices.
- High-Precision Arithmetic: Adding and multiplying strings.
- Two Pointers: Tackling challenges like finding the longest substring without repeating characters.
Data Structures
- Linked Lists & Stacks: Challenges in manipulating linked lists and utilizing stacks for solving complex tasks like evaluating daily temperatures.
- Queues: Using monotonic queues to solve problems like finding sliding window maximums.
- Hashing: Implementing hash tables for various tasks, ensuring efficient data retrieval and storage.
Search Techniques
- Breadth-First Search (BFS): Solving shortest path problems in complex networks like matrices and graphs.
- Depth-First Search (DFS): Effective in challenges demanding thorough exploration such as word search puzzles.
Dynamic Programming (DP)
- Linear DP: Tackles standard problems like Pascal’s Triangle and Minimum Path Sum.
- Longest Increasing Subsequence: Optimizing various sequences through methodical dynamic programming.
- Knapsack Problems: Encounter 0-1 and complete knapsack problems with solutions that explore all possible combinations efficiently.
Specialized Practices
