lect13c
optional loops exercises

We'll talk about returned homework, and finish up lect13b—finishing loops.

Shuffling with lists (optional)

We'll divide the class into three teams, each writing one function:

• A function which takes a String and returns a list of its characters.
• A function which takes a list of characters, and returns a new list of those same characters but in a random order.
• A function which takes a list of characters, and returns a String.
• The executive team, which writes a function shuffleString.
  Once that's working, make a version which shuffles all but the first-and-last letters.
