so i had this question for my finals today : take 3 integers from the command line and print them in descending order. i did it without sorting :)

gistfile1.java

class f{
    public static int max(int x, int y){
        return (x > y) ? x : y;
    }

    public static int min(int x, int y){
        return (x < y) ? x : y;
    }

    public static void main(String [] args){
        int i, hi, mid, lo, x1 = 0, x2 = 0;
        if (args.length != 3) return;
        int arr[] = new int[3];
        for (i=0; i<3; i++) arr[i] = Integer.parseInt(args[i]);
        hi = max(max(arr[0], arr[1]), arr[2]);
        lo = min(min(arr[0], arr[1]), arr[2]);
        for (i=0; i<3; i++) x1^=arr[i];
        x2^=hi;
        x2^=lo;
        mid = x1^x2;
        System.out.printf("%d %d %d\n", hi, mid, lo);
    }
}
