Is this the same person who coded the odd/even function?

[–] [email protected] 34 points 11 months ago* (last edited 11 months ago) (16 children)

I have a better odd/even function:

bool isEven( long long x ) {  
  if ( x &lt; 0 ) x = -x;  
  if ( x == 1 )  
    return false;  
  if ( x == 2 )  
    return true;  
  return isEven( x - 2 );  
}

This will work for both negative numbers and arbitrarily large integers. I've tested it up to 26 but I'm pretty sure it will work up to infinity.

Though serious question: Why are these forums coded in such a way that they ignore single newlines? How hard is it to replace a newline with a br tag?

Edit: added two spaces, should look much better.

Edit2: just looks a bit better lol

Edit3: better now?

It’s Markdown syntax. You can actually format it nicely in a code block:

bool isEven( long long x ) {
  if ( x &lt; 0 ) x = -x;
  if ( x == 1 )
    return false;
  if ( x == 2 )
    return true;
  return isEven( x - 2 );
}

You do that by adding ``` above and below it. To force single line breaks, you can terminate your sentences with two spaces, or a backslash.

Ah thank you, the editor in connect isn't great and doesn't have the markdown guide or buttons for the preformatted block, so I couldn't find the character combo to use it (and never would have guessed that lol). Also it keeps giving an error when I edit, though the edit is going through.
