package main
// ---------------------------------------------------------
// EXERCISE: Infinite Kill
//
// 1. Create an infinite loop
// 2. On each step of the loop print a random character.
// 3. And, sleep for 250 milliseconds.
// 4. Run the program and wait a couple of seconds
// then kill it using CTRL+C keys
//
// RESTRICTIONS
// 1. Print one of those characters randomly: \ / | -
// 2. Before printing a character print also this
// escape sequence: \r
//
// Like this: "\r/", or this: "\r|", and so on...
//
// 3. NOTE : If you're using Go Playground, use "\f" instead of "\r"
//
// HINTS
// 1. Use `time.Sleep` to sleep.
// 2. You should pass a `time.Duration` value to it.
// 3. Check out the Go online documentation for the
// `Millisecond` constant.
// 4. When printing, do not use a newline! Or a Println!
// Use Print or Printf instead.
//
// NOTE
// If this exercise is hard for you now, wait until the
// lucky number lecture. Even then so, then just skip it.
//
// You can return back to it afterwards.
//
// EXPECTED OUTPUT
// - The program should display the following messages in any order.
// - And, the first character (\, -, /, or |) should be randomly
// displayed.
// - \r or \f sequence will clear the line.
//
// \ Please Wait. Processing....
// - Please Wait. Processing....
// / Please Wait. Processing....
// | Please Wait. Processing....
