대법원 인명용 한자 바인딩(Combine Hangul and Chinese characters) - 17 entries

The character system of Chinese characters has caused difficulties in character encoding for a long time. The content is to link the Korean name and the corresponding Chinese character. input is simply pasted Chinese table, and you need to make it in json format. Most of them are omitted because there are too many Chinese characters, but I think it's better to work from "가" to "힐". There are a few rules here. 1. One Hangul must correspond to multiple Chinese characters. 2. In the case of "a(b c)", "a" is a redundant Chinese character, so you must remove "a" and use only "b c". 3. There are some characters here that don't appear to be an encoding issue, but they should all be used. 4. Should follow json format, Chinese characters are arrays. 문자인코딩의 역사속에서 한문은 여러가지 난제를 만들어왔습니다. 이 문제는 대법원 인명용 한자를 바인딩하는 것입니다. input은 단순히 인명용한자 표를 붙여넣기 한 것이며, 이것을 json형식으로 만들어야합니다. 한자가 너무 많은 관계로 대부분을 생략하였으나, 기본적으로 "가"부터 "힐"까지 모두 동작하는 것이 좋다고 생각합니다. 여기에는 몇가지 규칙이 있습니다. 1. 한글 하나에는 여러개의 한자가 대응합니다. 2. "a(b c)"같은 경우 "a"는 중복된 한자이므로, "a"를 제거하고 "b c"만을 사용해야합니다. 3. 몇몇 한자는 인코딩의 문제로 보이지 않을 수 있습니다. 그러나 모두 사용해야합니다. 4. json형식을 따르며, 한자는 배열입니다.

vimtutor, but you can cheat - 13 entries

It's time to revisit vimtutor, but as an experienced Vim user! Your goal is to change the file to appear as if you had gone through the tutorial, but you do NOT need to actually complete the tutorial as written or do anything that doesn't result in changes to the file. You may use whatever you have in your Vim toolbelt that's allowed under VimGolf rules. The whole tutorial is too large to submit, so only the relevant lesson headers and associated practice lines are presented in this challenge. You will have to reference the tutor for the original instructions if you need them: https://raw.githubusercontent.com/vim/vim/4466ad6baa22485abb1147aca3340cced4778a66/runtime/tutor/tutor

Change double quotes to single quotes, but with a twist - 214 entries

Although this challenge is in the context of a Python function, you don't need to know Python to do this challenge. It is to add contexts and interesting constraints. The file contains a function that prints a multi-line string literal. I wrote the string literal with double quotes, but then I decided to use single quotes instead, and that's your challenge. However, interestingly enough, the string itself contains single and double quotes. This means, inside the string literal, the originally escaped double quotes no longer need to be escaped, but the single quotes now need to be escaped. Note that the triple double quotes in the docstring should be left alone.
