Retake your solution to Exercise 11-1 and split the module’s interface from its implementation by moving all function definitions to an implementation file. Do not use namespace blocks in the implementation file. As part of the exercise, move all nonexported functions out of the words namespace and into the global namespace (and then figure out how to still invoke the ternary sort() function from the exported unary sort() function).
