The Rules
- Each submission must be a full program or a function.
- The program must take all instances of the string
2015from the input (1 string), replace it with<s>2015</s>*(with <s> or <strike>). At the end, if there has been at least one2015in the string, you must add a newline and this string:*2016. I'm a year early! - The program must not write anything to STDERR.
The input will not contain
<s>2015</s>or<strike>2015</strike>.Note that there must be an interpreter so the submission can be tested.
- Submissions are scored in bytes, in an appropriate (pre-existing) encoding, usually (but not necessarily) UTF-8. Some languages, like Folders, are a bit tricky to score - if in doubt, please ask on Meta.
- This is code-golf, so shortest code wins
Examples
Input:
Hello! The date is 2015-12-24.
Output:
Hello! The date is2015*-12-24. *2016. I'm a year early!
Input:
foo bar baz quux
Output:
foo bar baz quux
Input:
12320151203205120151294201511271823
Output:
1232015*120320512015*12942015*11271823 *2016. I'm a year early!
Input:
Hello. The year is 2015... 2015.5...
Output:
Hello. The year is2015*...2015*.5... *2016. I'm a year early!
The Snippet
The Stack Snippet at the bottom of this post generates the catalogue from the answers a) as a leaderboard and b) as a list of winners per language.
To make sure that your answer shows up, please start your answer with a headline, using the following Markdown template:
## Language Name, N bytes
where N is the size of your submission. If you improve your score, you can keep old scores in the headline, by striking them through. For instance:
## Ruby, <s>104</s> <s>101</s> 96 bytes
If there you want to include multiple numbers in your header (e.g. because your score is the sum of two files or you want to list interpreter flag penalties separately), make sure that the actual score is the last number in the header:
## Perl, 43 + 2 (-p flag) = 45 bytes
You can also make the language name a link which will then show up in the snippet:
## [><>](http://esolangs.org/wiki/Fish), 121 bytes

Can we use
<strike>? – Downgoat – 2016-01-02T01:21:26.337I'm not sure if that would allow you to make it shorter. – ev3commander – 2016-01-02T01:23:22.257
@BlockCoder1392 It might.
"asdf".strike()is javascript. – Conor O'Brien – 2016-01-02T01:27:33.827Hmm... sure. I'll add it to the post – ev3commander – 2016-01-02T01:29:33.930
Can the input contain
<s>2015</s>*? – Martin Ender – 2016-01-02T01:30:43.973No. The input will not contain
<s>2015</s>or<strike>2015</strike>. – ev3commander – 2016-01-02T01:33:33.8631@downvoters what is wrong with this challenge? – ev3commander – 2016-01-02T01:41:10.000
15I find the challenge boring. It's a find-replace followed by a conditional concatenated string. Also, I don't like when functions are disallowed for no particular reason. – xnor – 2016-01-02T01:45:39.217
@xnor ... To quote NBZ, "Because there are not enough simple code-golf challenges" – ev3commander – 2016-01-02T01:47:24.733
8Yes, but a challenge can be simple without being straightforward. Replacement or regex is a built-in in most langs. It means that's likely just the way to do it. – xnor – 2016-01-02T01:49:16.457
2Can we have any trailing whitespace? – Downgoat – 2016-01-02T02:30:51.900
4Not everyone agrees with @NBZ on that. And there are certainly more than enough trivial questions. If you post questions which have a negative score in the sandbox, don't be surprised to see them downvoted. – Peter Taylor – 2016-01-02T14:57:50.260
@Doᴡɴɢᴏᴀᴛ No trailing whitespace. – ev3commander – 2016-01-02T17:00:31.707
Will the input have newlines – Downgoat – 2016-01-02T19:39:48.660
Your code has to accept new lines. – ev3commander – 2016-01-02T19:43:09.783
instead of "replace it with
<s>2015</s> (with <s> or <strike>)and put an asterisk to the right of it" you could just say "replace it with<s>2015</s>*– Cyoce – 2016-01-02T20:14:16.630
