Q. Write an algorithm to Swap Two Numbers without using temp variable.

1. Start
2. Read two integers `x` and `y` from the user
3. Display the values of `x` and `y` before swapping
4. Perform swapping:
    - Set `x = x + y`
    - Set `y = x - y` (which is original `x`)
    - Set `x = x - y` (which is original `y`)
5. Display the values of `x` and `y` after swapping
6. End
