List of Kata with Images in Description - codewars/content-issues GitHub Wiki

Maybe some of the images can be improved/fixed:

  • formulas can be replaced with KaTeX (some of them are obvious from alt text or URL)
  • image of text can be replaced with text
  • simple diagrams can be replaced with ASCII art
  • broken image links

The code block under the name is strings matching pattern /(:?!\[[^\]]*\]\([^)]+\))|(?:<img [^>]+\/?>)/g truncated.
