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
[java]
class Incr{
public static void main(String … args){
Integer x = 7;
int y = 2;x __ __ ;
__ __ __;
__ __ __;
__ __ __;
System.out.println(x);
}
}
[/java]
The allowed fragments:
| y | y | y | y |
| y | x | x | |
| -= | *= | *= | *= |
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?
Piece of cake!
Yeah right, and the answer is? Did you mail that to Peter?
