The idea is simple. You've to create a "visualised" letter-replacement, by providing 3 strings (input can be comma separated, separate inputs, or as an array). The first segment is the word you want to correct, and the second segment is the letters you want to replace, and the third segment is the replacement for the letters in segment 2.
For example:
| | Input | Starting Word | Output |
|----|-----------------------------|---------------|-------------|
| #1 | Hello world -wo -ld +Ea +th | Hello world | Hello Earth |
| #2 | Hello World -wo -ld +Ea +th | Hello World | Hello Worth |
| #3 | Hello -llo +y | Hello | Hey |
| #4 | Red -R -d +Gr +en | Red | Green |
| #5 | mississippi -is -i +lz +p | mississippi | mlzslzspppp |
| #6 | Football -o -a +a +i | Football | Fiitbill |
| #7 | mississippi -is -i +iz +p | mississippi | mpzspzspppp |
Explanation
The replacements are to be done step-by-step with their respective pair. Here's an illustration with an input of mississippi -is -i +iz +p
to give the output mpzspzsppp
(see example #7
above)
| Step | Input | Output |
|------ |--------------------------- |------------- |
| #1 | mississippi -is -i +iz +p | |
| #2 | mississippi -is +iz | mizsizsippi |
| #3 | mizsizsippi -i +p | mpzspzspppp |
Rules
- Inputs are always in this order
<starting_string> <list_of_letters_to_replace> <replacement_letters>
. - Letters to replace and replacement groups will never be mixed (ie: there will never be
-a +i -e +o
). - Letters to replace are always prefixed with
-
and replacement letters are always prefixed with+
. (The prefix is mandatory) - There may be more than one set of letters to replace, so you'd need to look at the prefix.
- Assume the amount of letter groups to replace and the amount of replacement letter groups are always equal (ie: there will never be
-a -e +i
) - Replacements are case-sensitive (see example
#1
and#2
). - Replacements are done in the order they were given in the input.
- Letter replacements can be replaced with other replacements. See example
#6
. - The first segment (starting word) will never include
-
or+
characters. - This is code-golf so shortest bytes win.
Leaderboards
Here is a Stack Snippet to generate both a regular leaderboard and an overview of winners by 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 leaderboard snippet:
# [><>](http://esolangs.org/wiki/Fish), 121 bytes
