 The function should return the position of the pellet that is "closest" to PacMan. One implementation could be
 to sort the vector of pellets by the distance they have to PacMan, and then return the first one.
 
-*Hint 1*: use the `positionDistance` function to find the distance to PacMan
-*Hint 2*: use the [std::sort](https://en.cppreference.com/w/cpp/algorithm/sort) function to sort the vector
