Editor's note: that's my first challenge, don't judge strictly.
In Xyzzy Corp. we use a special markup language, but we still need a parser from that language to HTML. Here are the basic rules:
To make text bold, surround it with {*} in the beginning and [*] in the end. So, {*}text[*] results ...
Clean numbers
We call a positive integer a clean number if it is expressible by using only a positive digit once or more and no other sign. For example 88 is expressible with 2's as 2222.
A more complex example is
$141289730531295606313143345858933 = 3^{33}3^{3^3}3333$

Write a program in JAVA to generate all the possible 4-digit numbers using any given 4 digits(e.g.4,6,2,8) without array or manually printing the numbers.
What is the most recommended way to include large test cases in a question?
Small test cases can be included in the question, but large test cases might go over the character limit or take up a lot of space, making the question cluttered.
Add two numbers (or Arithmetic on continued fraction expansions)
code-golf math
Given two continued fraction expansions N,M as lists of integers (in any suitable (human readable) format for your language) and an operation @ (addition, substraction, multiplication and division) +-* or / (e.g. en...
Your challenge:
You are on the 0th floor of a infinitely tall building. At any floor, you can walk to the window and drop an egg. Your goal is to figure out the highest floor that the egg can withstand without breaking. However, you have a maximum of 3 eggs to use to figure this out, but you n...
As you may or may not know, we briefly had MathJax support on our main site. However, it caused all sorts of problems and was removed. For whatever reason, MathJax support was not removed on meta. While this doesn't affect typical questions posted on meta, it causes issues in the Sandbox when use...
