一道簡單面試題：兩個整型不借助中間變量實現值互換

一道簡單面試題：兩個整型不借助中間變量實現值互換的兩種算法
C# Code:

using System;
namespace KiloNet
{
    class test2 
    {
        static void Main(string[] args)
        {
            int a = int.MaxValue;
            int b =  int.MaxValue-2;
            Console.WriteLine("a:{0},b:{1}",a,b);

            a = b + (b = a) * 0;
            Console.WriteLine("a:{0},b:{1}",a,b);
            
            a = a^b;
            b = a^b;
            a= b^a;
            Console.WriteLine("a:{0},b:{1}",a,b);
            Console.Read();
        }
    }
}

//java code 饅頭所有
class test 
{
    public static void main(String[] args) 
    {
        System.out.println("Hello Kilo!");
        int a = 34;
        int b = 45;
        System.out.println("a="+a + ",b="+ b);

        a = a^b;
        b = a^b;
        a= b^a;
        System.out.println("a="+a + ",b="+ b);

        a = a+b;
        b = a-b;
        a= a-b;
        System.out.println("a="+a + ",b="+ b);

    }
}

//哈哈，這是Java2里看到.
