Answer 
There are various ways using operators and expressions. The simplest way is always recommended with some physical world scenarios.
As you asked for algorithm only.
Declare and initialize two variables first, second
Step 1 → Add first and second and store to first
Step 2 → Subtract second from first and store to second
Step 3 → Subtract second from first and store to first
Swap completed.
Insight:
Assuming variable having value first=10 and second=20
Now adding first with second and storing the result 10+20=30 in first.
Now subtracting the second which is still 10 from first and storing the result 30-10=20 in second
Here we achieved the initial swap
Then subtracting second which is 20 from first 30-20=10 and storing the result in first complene the final swap as now value inside variable first is 10 and second is 20.
Thank you
