Instructions

2015 has been quite a year for elixir, and we wanted a way to celebrate the comming New Year. We are thrilled that this weeks puzzle was dreamed up by one of our contributors, @stoftis. So if you have any puzzle ideas let us know, through email or twitter https://twitter.com/elixirgolf.

The puzzle is to create a countdown timer that displays the number of Days:Hours:Minutes:Seconds until the next New Year. This countdown timer will decrease every second until 000:00:00:00.

$ elixir countdown.exs
013:05:49:08

Rules

  • The code will be executed using the elixir countdown.exs terminal command. We will manually copy all your solutions into this file, so please just submit your solutions as below.
  • The timer will be in the following format Days:Hours:Minutes:Seconds
  • The time should be represented as numbers, separated by colons: 000:00:00:00
  • Every second the timer should decrease by 1 second, and all the other fields should adjust accordingly:
013:05:00:01
013:05:00:00
013:04:59:59
013:04:59:58
..
..
000:00:00:03
000:00:00:02
000:00:00:01
000:00:00:00
  • The timer should only display one timer at any time, i.e. it should have some mechanism to clear the screen or update itself every second. It should NOT display a long list of times, like the example above.
  • The timer should countdown to the next New Year e.g. January 1st 2016.

Bonus Credits

As a bit of fun and a side project maybe consider the following flourishes:

  • Colour the numbers
  • Allow the countdown timer to dynamically adjust to the following New Year after this one
  • Trigger some exciting output when the countdown reaches 000:00:00:00.
