Describe the process of input/output and mutable state management in Haskell.

In Haskell, a purely functional programming language, the concept of mutable state is handled differently compared to imperative programming languages. Rather than directly mutating state, Haskell embraces immutability and uses a combination of functional programming techniques to manage state. Additionally, input/output (I/O) operations are handled in a pure and referentially transparent manner through the use of monads. Let's explore the process of I/O and mutable state management in Haskell. Input/Output (I/O) Operations: Haskell's approach to I/O is based on the idea of separating pure computations from side-effecting actions. This is achieved through the use of monads, specifically the `IO` monad. The `IO` monad allows you to describe and sequence I/O actions in a pure and composable manner, ensuring referential transparency. To perform I/O in Haskell, you define a main function of type `IO ()`, which serves as the entry point of your program. Within the main function, you can use various functions provided ....
