Thank you

Sorry, it isn't an issue. I am working on a similar project and just want to say explicitly: Thank you a lot for keeping records of algorithm changes and being so active, it's very helpful!

Regex for iteration/case 0 breaks on filename with special characters

Hi, thanks for your work in this. I noticed that the script silently breaks when the filename has special characters like ! inside it. Here is a minimal example

package main

import (
	"fmt"
	"regexp"
)

func main() {
	raw := `document.getElementById('dlbutton').href = "/d/EP04EZxQ/" + (597700 % 51245 + 597700 % 913) + "/!.txt";`
	r := regexp.MustCompile(`document\.getElementById\('dlbutton'\)\.href\s*=\s*"/d/(\w+)/"\s*\+\s*([\d\w\s+\-*/%()]+?)\s*\+\s*"/([/\w%.-]+)";?`)
	m := r.FindStringSubmatch(raw)
	fmt.Println(m)
}

The reason is the last regex [/\w%.-]+ which breaks with a filename of !.txt. ! is a valid identifier in the URLs. So maybe we should just make it .+ instead? This holds for iteration/cases 1 and 3 as well.

I would also like to provide some suggestions to make the code more readable:

• Use raw string in the regexp so that you don't need to do multiple layers of escaping
• Inside TryMakeZippyFile, print a message when all iterations fail instead of silently exiting
