Dados dos números x e y, necesitamos intercambiar sus valores
Ejemplos:
Input : x = 10, y = 20; Output : x = 20, y = 10 Input : x = 200, y = 100 Output : x = 100, y = 200
Java
// Java program to swap two variables
public class GfG {
public static void main(String[] args)
{
int x = 100, y = 200;
System.out.println("Before Swap");
System.out.println("x = " + x);
System.out.println("y = " + y);
int temp = x;
x = y;
y = temp;
System.out.println("After swap");
System.out.println("x = " + x);
System.out.println("y = " + y);
}
}
