Thanks to all the replies!
It seems that there are ways to solve the exercise if I use constructs
that are found in later chapters of the book. Sean could be right in
that some of the exercises are meant to be difficult to solve and they
prepare you for later chapters.
Tried Gour's suggestion, but didn't work for
howManyOfFourEqual 4 4 2 2 = 3
Anyway the approach was similar to mine, and if I use isEqual I could
get a simpler solution.
Thanks again.
