Sequence types

Sequence types are data structures used in programming to store ordered collections of items, like lists of numbers or words. They keep everything in a specific order, so you can access each element by its position, starting from zero. Common examples include lists (which can hold different types of items) and strings (sequences of characters). Sequences are flexible and useful for organizing and working with multiple related pieces of data, allowing for easy iteration, modification, and retrieval based on position.
