Arrays
Visualize array operations, sorting, and searching algorithms
Arrays are fundamental data structures that store elements in contiguous memory locations. They provide constant-time access to elements using indices and are the foundation for many other data structures and algorithms.
Key Concepts
- Random access in O(1) time using indices
- Fixed or dynamic size depending on implementation
- Cache-friendly due to contiguous memory
- Foundation for sorting and searching algorithms
- Efficient iteration and bulk operations
