Short Response Questions

1. There are four sorting algorithms listed below. For each one, please provide:

   • A detailed explanation of how the algorithm works
   • The space and time complexity in Big O notation
   • Some cases when you might prefer or not prefer this algorithm over others (i.e. "This algorithm performs well if the list is already nearly sorted")

Coding Exercises

1. In the exercises.js file, implement each of the sorting algorithms above without using JavaScript's built-in Array.prototype.sort() method. Each of the functions has been stubbed out for you, but you are welcome to create your own helper functions if needed.
