How can higher-order functions be used in Kotlin, and what benefits do they provide?

In Kotlin, higher-order functions are functions that can accept other functions as parameters or return functions as results. They allow you to treat functions as first-class citizens, enabling powerful and flexible programming paradigms such as functional programming. Higher-order functions provide several benefits in terms of code reuse, abstraction, and expressiveness. 1. Code Reuse: Higher-order functions promote code reuse by abstracting common patterns into reusable functions. By accepting functions as parameters, higher-order functions allow you to pass different behaviors to a single function, reducing code duplication. This promotes modular and maintainable code, as you can define generic functions that can be used with different behaviors based on the function parameters. 2. Abstraction: Higher-order functions enable abstraction by encapsulating complex behavior into smaller, reusable functions. They allow you to define higher-level operations that can be applied to various data structures or contexts. This abstraction leads to cleaner and more concise code,....
