My wife doesn't really like coding, she can find her way around HTML, CSS en some Javascript... but only if I really don't feel like doing it for her. Can't blame her, she is a designer.

She does however like making puzzles, specifically numerical puzzles like sudoku.

While preparing for the upcoming exam I stumbled over the following question, which I asked her to try and figure out.

Place the fragments into the code to produce the output 33. Note, you MUST use each fragment exactly once

PLAIN TEXT

JAVA:

1. class Incr{
2.   public static void main(String ... args){
3.     Integer x = 7;
4.     int y = 2;
5.  
6.     x __ __ ;
7.     __ __ __;
8.     __ __ __;
9.     __ __ __;
10.     System.out.println(x);
11.   }
12. }

The allowed fragments:

After introducing her to some basic concepts ( x *= x could be written x = x*x) she got to work, and managed to come up with the answer. Can you?
