Learn how to effectively swap two string variables without using a third variable in programming with this step-by-step guide.
// Scala program to swap two numbers// without using 3rd variableobjectSample{defmain(args:Array[String]){varnum1:Int=10;varnum2:Int=20;println("Numbers before swapping:")printf("\tNum1:%d\n",num1)printf("\tNum2:%d\n",num2)num1=num1+num2 num2=num1-num2 num1=num1-num2...
Given two variables, x and y, swap two variables without using a third variable. Example Given x =10, y =5 Return15. 思路:考察位运算,异或。 同一个数异或两次还是其本身。 1classSolution {2public:3/**4* @param x an integer5* @param y an integer6* @return nothing7*/8voidswap(int&...
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 without using third variable objectmyObject{defmain(args:Array[String]):Unit={vara=10varb=20println("Values before swapping:...
Suppose you have two variables x and y and you want to swap their values. The usual way to do this is using another temporary variable: temp = x; x = y; y = temp; However, the interchange of two variables can be done without the temp variable: ...
The logic toswap the two arrays without using a third variableis as follows ? for(i=0;i<size;i++){first[i]=first[i]+sec[i];sec[i]=first[i]-sec[i];first[i]=first[i]-sec[i];} Program The following C program swaps two arrays without using a temporary variable. It reads the...

The simplest method to swap two variables is to use a third temporary variable : define swap(x, y) temp := x x := y y := temp Sample Solution: JavaScript Code: // Declare and initialize two variables, x and y, with the values 20 and 40, respectively.letx=20;lety=40;// Output...
This involves creating a third variable, assigning one of the original variables to it, assigning the value of the second variable to the first variable, and then assigning the value ofthe temporary variable to the second variable. This effectively swaps the values of the two variables without ...
