Swapping the values of two variables
Let us warm up your brain with something simple first. 🔥ðŸ§
Now, if you recall - back in Lesson 2 we talked about variable assignments.
Now, let us say we have two variables x, and y:
x = 15
y = 24
We would like to swap the values of the variables. After swapping, we want x to be pointing to what y was pointing (24 in our example); and we want y to be pointing to what x was pointing (15 in this example).
How would you do this?
Try this, and make sure that the value of x is 24 and y is 15 in the end.
