Review Paper On: Array Manipulation Techniques

Abstract

This review presents a systematic analysis of four fundamental array manipulation techniques— traversal, searching, two-pointer approach, and sliding window paradigm—that are critical for developing efficient algorithms. We examine linear and specialized traversal methods, compare brute-force and binary search algorithms, and analyse two-pointer variations (same-direction and opposite-end) for optimization problems. The sliding window technique is explored for both fixed and dynamic window scenarios in subarray problems. Beyond theoretical foundations, this work synthesizes practical insights, performance trade-offs, and implementation challenges, bridging the gap between algorithmic principles and real-world applications. By providing a structured framework for selecting and optimizing array-based solutions, this review serves as an essential resource for researchers and practitioners advancing algorithm design.
