Sliding Window
The sliding window is an optimization technique used to solve problems involving arrays or strings by maintaining a subset (window) of elements and moving it across the data. It reduces unnecessary recalculations, making it efficient for tasks like subarray sums, maximum/minimum ranges and pattern matching, often achieving O(n) time complexity.

In databases, a query is a request to retrieve, insert, update or delete data. Written in SQL (Structured Query Language), queries can be simple, like fetching all rows from a table, or complex, involving joins, conditions and aggregations. They are essential for interacting with and managing database information efficiently.

Git is a distributed version control system used to track changes in code, collaborate with teams and manage project history. It allows developers to work independently on branches, merge updates and revert to previous versions when needed. Git ensures code integrity, supports parallel development, and is widely used in software engineering for efficient source code management and collaboration.
An array is a linear data structure that stores multiple elements of the same type in contiguous memory locations. It allows fast access using index positions, making operations like retrieval efficient. Arrays are widely used for organizing data, implementing algorithms and building other data structures. However, their size is fixed, making resizing difficult compared to dynamic collections.
