This article provides a comprehensive overview of the Quick Sort algorithm, a highly efficient comparison-based sorting method. It covers the core divide-and-conquer logic, analyzes its performance in best, worst, and average scenarios (ranging from $O(n \log n)$ to $O(n^2)$), and discusses critical optimization strategies like pivot selection methods (median-of-three, randomized). Complete with clear pseudocode and implementations in Java and C.

Understanding and Handling Deadlock in Operating Systems
January 2, 2020
A comprehensive guide to understanding deadlock in operating systems. This post defines deadlock, demonstrates how to model it using resource allocation graphs and state transitions, and covers various detection algorithms for both general and single-unit resources. It also explains dynamic deadlock avoidance, specifically the Banker's Algorithm, and effective strategies for deadlock prevention by breaking necessary conditions like hold-and-wait and circular wait.
