  • In this simple challenge, create a short program that takes 2 `int`s 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):
  • ```c
  • #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.

Small integer swapping
In this simple challenge, create a short program that takes 2 `int`s as input, output them, swap their places, then output them again. The program with the shortest solution wins!

However, you can't do something like:
```
print(x,y)
print(y,x)
```

I'd call that a loophole. Loopholes are banned in this challenge.

An example C program for the challenge (mostly ungolfed):

```c
#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);
}
```
