Question 2: Scrabble Sorting
Sometimes when sorting, we want to sort using a property of each value, instead of the value itself. Then we have to consider what to do for values for which the property is equal. Which should we prefer? criterion is unchanged. previously came after “was”, and now comes before.
Think about modelling your solution upon the insertion sort algorithm shown in Lesson 06.4, and writing your own helper function to compare two words. If a word appears multiple times in the input list, it should appear the same number of times in the result.
You may use your own solution to the Scrabble scoring problem from Assignment 4. If you prefer, you may use the posted solution, once it is available.

CS 115 – Introduction to Computer Science 1
School of Computer Science
University of Waterloo
Where to Begin
Welcome to CS 115!The Winter 2022 term offering of this course will be delivered through UW Online: online.cs.uwaterloo.ca.
Directions on how to access this site can be found on Learn.
Course Philosophy
CS 115 has been designed with the diverse interests, backgrounds, and goals of students always in mind. As we are aware of the varied ways in which this material might be of use in the future, we have included concepts that are beautiful and universal. The focus of the course is foundational concepts in computer science (rather than the mechanics of programming) and ways of thinking about computation (rather than solving tasks in a rote fashion). Students will learn skills that are applicable to new languages and environments, not just those used in the course. Because of the fundamental nature of the concepts taught in CS 115, the course can serve both students whose primary interest in computers is in their use in their chosen areas of study and students intending to minor in CS.
