We can also swap two numbers without using the third variable. This method saves computation space hence is more effective. Let, variableacontains first value, variablebcontains second value. Step 1: a = a + b Step 2: a = a - b Step 3: b = a - b Scala code to swap two number ...
Swapping of two numbers in C Language is the process in which the value of two variables is exchanged using some code. For example,a = 5, b = 4 // After swapping: a = 4, b = 5We can swap two numbers in various ways as follows:Swapping two variable values using a Temporary ...
下图中,当px和py作为参数,进行方法调用时,实际上会生成px和py的一份”拷贝”,注意拷贝的是px和py的值.然后把这对值传入了方法,交换结束后,argx和argy各自指向了新的对象实例,但是方法之外的px和py并没有变化,这就是对象实例交换失败的原因。 Tricky Code JavaWorld的一个问题中,Tony Sintes给出了下面一段Tric...
