A solution to last week’s challenge can be found here.https://commons.wikimedia.org/wiki/File:Olympic_rings_without_rims.svg

As we gear up for the 2021 Summer Olympics, let's take a look back at the countries and athletes that participated in the last Summer Olympics.

- The "athletes" dataset contains data about the athletes who competed in the 2016 Summer Olympics in Rio de Janeiro.
- The "countries" dataset contains the International Olympic Committee country code.

Find the following for each country:
- The sport with the most athletes
- The total number of athletes
- The total number of female athletes
- The total number of male athletes, and
- The average age of all athletes for each country

14 - Magnetar

Sprint finish.

Looks like there's a few erroneous nulls in the solution. This will be because a number + Null() = Null(). Gotta zero those nulls first.

11 - Bolide

Let the games begin!

12 - Quasar

Made sure to use the start date for the Rio Olympics when calculating the athlete's ages.
