  2. Write a sorting algorithm that can sort n number of high scores (float Score, string Name) by score. What algorithm did you use? How does this algorithm scale? Can you reduce time and space complexity?
  3. Given two three-letter words, write a program that will determine the amount of "moves" it takes to change one word to the other. A "move" is considered changing a single letter of the given word while still keeping it a valid three-letter word. Note: A full list of three-letter words is provided in this repository as [three-letter-words.txt] (
