Data structures are used to organize and store data, and can vary based on the type of data and the desired operations.Linear data structures like arrays and linked lists organize elements sequentially.Non-linear data structures like trees and graphs allow for relationships between elements at different levels.Arrays group similar data elements together in one place but are limited to a single data type.Linked lists are beneficial for inserting and deleting elements within the list efficiently.Queues are useful for managing elements at the start and end of a list, allowing for easy insertion and removal.Stacks simplify removing elements from the list without adding new ones.Trees establish hierarchical relationships among data elements, ideal for complex operations and dependencies.Heaps, a specialized type of binary tree, are effective for managing varying priorities of data elements.Graphs model relationships and dependencies between data elements, offering flexibility in representing connections.
