Array slicing is a technique used to extract a subset of elements from an array, allowing for efficient data manipulation and retrieval without altering the original structure. It is widely used in programming languages like Python and NumPy to access specific parts of data structures using a range of indices, often in a concise and readable manner.

Efficient Data Manipulation

Data retrieval is the process of identifying and extracting relevant data from a database or data storage system for further processing or analysis. It involves using specific queries or search techniques to obtain precise information quickly and efficiently, often leveraging indexing and optimization strategies to enhance performance.
