Small integer swapping
In this simple challenge, create a short program that takes 2 ints as input, output them, swap their places, then output them again. Those 2 integers can't be the same number. The program with the shortest solution wins! Loopholes are banned in this challenge.
An example C program for the challenge (mostly ungolfed):
#include <stdio.h>
int main() {
int x, y;
scanf("%i %i", &x, &y);
printf("%i %i", x, y);
int z = x;
x = y;
y = z;
printf("%i %i", x, y);
}
You can make 2 answers in one post: 1 with output swapping, and 1 with variable swapping.
