Seinfeld-Inspired Haskell Program

Overview

This Haskell program is inspired by Season 7, Episode 24 of Seinfeld. In a memorable scene, the character Kramer visits a bank that offers $100 to anyone not greeted with a "hello." Instead of "hello," Kramer is greeted with "hey," and he insists that this doesn't count, leading to a humorous negotiation with the bank manager.

Our program mimics this scenario by evaluating user-inputted greetings and assigning different values based on the greeting.

How It Works

The processString Function

• "hello": If the input starts with "hello" (ignoring case and leading spaces), the function returns 0, just like the bank's promise.
• 'h': If the input starts with the letter 'h' (but isn't "hello"), the function returns 20.
• Anything Else: For any other greeting, the function returns 100, reflecting Kramer's argument that the greeting isn't "hello."

The main Function

• The program runs in a loop, asking the user to input a greeting.
• After processing the input with processString, it displays the corresponding result.
• The loop continues until the user types 'e' to exit.

Usage

Running the Program

1. Enter a Greeting:

   • Type any greeting, such as "hello," "hey," or anything else.
   • Example:
     • Input: hello
     • Output: Result: 0 $

2. Exit:

   • To quit, type e.
   • The program will display a message and stop running.

Example Interactions

• Example 1:
  Input: hello
  Output: Result: 0 $

• Example 2:
  Input: hey
  Output: Result: 20 $

• Example 3:
  Input: good morning
  Output: Result: 100 $

Purpose

This playful piece of code is a homage to a classic Seinfeld moment, showing how simple logic can mimic real-world situations. It's perfect for fans of the show or anyone learning Haskell.

Enjoy the program, and remember—if you’re ever at a bank offering $100 for a "hello," be sure to check exactly what they say!
