Description

A pretty common task, especially for new programmers, is to ask the user to type in some value at the command line and then have the program act on it. (think "interactive maze game", "determine if word is palindrome", etc). It would be nice if we had an example in the os package showing how to do this.

Contributor guide

Research direction
Examine existing examples in the `os` package, then write a simple example demonstrating reading from stdin using `os.Stdin` and a scanner. Follow the Go documentation conventions for examples.
