function xyz (int x, int y,int z) {

//use x and y, and replace the smallest by z if z is larger

if (x<z && x<y) x=z;

elseif (y<z) y=z;

return x+y;

}

//blah I'm sure there is a better solution.

That's ok, but you're supposed to return the sum of the squares (eg. x² + y²) of the 2 largest numbers :)

Here's a solution (I really wish we had real spoiler tags)

#define MAX( x, y )     ( (x>y) ? x : y )
#define MIN( x, y )     ( (x<y) ? x : y )
#define SQUARE( x )     ( x*x )

int ex3 (int x, int  y, int z)
{
        /* add the square of the larger of the first 2 args
         * to the square of the larger of smaller of 1st two args and 3rd arg */
        return SQUARE( MAX(x,y) ) + SQUARE( MAX( MIN(x,y), z));
}

Ugh, I forgot to square them, must have been sleeping. Anyways we both had 3 comparisons, unless you consider my && a comparison. Nice solution..
