There is a jar in which there are two types of candies.
20 blueberries and 16 strawberries. You perform the following steps:

You repeat these two steps till there is just one candy remaining in the jar. Which flavoured candy will be left?

Can you find out the remainder when 3^300 is divided by 5?
