Welcome to Kontext, a collection of programs, features, and tasks inspired by the LeetCode website. This repository is designed to help you explore and implement various algorithms and coding challenges. Whether you're a seasoned programmer or just getting started, Kontext provides a diverse set of tasks to enhance your coding skills.
- Simple Chat Implementation
- Semaphore Task
- Leetcode: Largest Element
- Leetcode: Shortest Palindrome
- Leetcode: Ugly Number
The Simple Chat Implementation is a basic chat program that uses threads. It consists of three modules:
- Client: This module utilizes Swing for the graphical user interface.
- Network: The network package contains classes responsible for handling network-related functionality.
- Server: The server package includes classes necessary for server-side operations.
The Semaphore Task in Kontext is designed to demonstrate the usage of semaphores, particularly in scenarios involving database operations. Semaphores help control access to shared resources and prevent race conditions.
The Semaphore Task implementation can be found in the semaphore_task directory. Follow the provided documentation and code comments to understand the solution.
The Largest Element task challenges you to find the largest element in a given array. This simple yet fundamental problem is useful for practicing array manipulation and basic algorithmic thinking.
Check the largest_element directory for the implementation of the Largest Element task. The solution is designed to be efficient and scalable.
The Shortest Palindrome task requires finding the shortest palindrome that can be obtained by adding characters to the beginning of a given string. This task is excellent for practicing string manipulation and pattern recognition.
Explore the shortest_palindrome directory for the implementation details. Follow the provided documentation to understand the approach taken to solve this task.
The Ugly Number task challenges you to determine whether a given number is an "ugly" number. An ugly number is a positive integer whose prime factors are limited to 2, 3, and 5. This task is useful for practicing number theory and basic algorithmic concepts.
Refer to the ugly_number directory for the implementation of the Ugly Number task. The solution demonstrates an efficient way to check if a number is "ugly."
