Explain the concept of collections in Scala and provide examples of different collection types.

In Scala, collections are an essential part of the language's standard library, providing a rich set of data structures and operations for working with groups of values. Collections in Scala are immutable by default, promoting functional programming principles, but mutable variants are also available when needed. The collections framework in Scala is designed to be efficient, expressive, and interoperable with other Scala features. Let's explore the concept of collections and examples of different collection types: 1. Immutable Collections: Immutable collections are the default in Scala and are preferred for functional programming. Once created, their content cannot be modified, ensuring referential transparency and safe concurrent access. * List: A List represents an ordered collection of elements of the same type. It provides fast access to the head (first element) and efficient creation of new lists by prepending elements. ``` scala`val numbers: List[Int] = List(1, 2, 3, 4)` ``` * Set: A Set represents a co....
