Question

Peter visits a bank that promises to give $100 to anyone who isn’t greeted with a “hello.” Kramer is instead greeted with a “hey,” which he insists isn’t a “hello,” and so he asks for $100. The bank’s manager proposes a compromise: “You got a greeting that starts with an ‘h,’ how does $20 sound?” Kramer accepts.

In a file called bank.py, implement a program that prompts the user for a greeting. If the greeting starts with “hello”, output $0. If the greeting starts with an “h” (but not “hello”), output $20. Otherwise, output $100. Ignore any leading whitespace in the user’s greeting, and treat the user’s greeting case-insensitively.
