Final challenges

You've mastered using stringr functions on their own, but by combining multiple operations together in sequence you can achieve quite complicated manipulations.

As the final exercise we want to expose you to the power of combining operations. You'll complete two tasks:

You'll turn a vector of full names, like "Bruce Wayne", into abbreviated names like "B. Wayne". This requires combining str_split(), str_sub() and str_c().
You'll compare how many boy names end in "ee" compared to girl names. This requires combining str_sub() with str_detect() along with the base function table().
