Discuss the concept of collections in Kotlin and provide examples of commonly used collection types.

They provide a convenient way to work with multiple values and perform various operations such as adding, removing, updating, and iterating over elements. Kotlin offers a rich set of collection types, each with its own characteristics and use cases. Let's explore some commonly used collection types in Kotlin: 1.
