Notes:

• For all exercises, to receive credit you need to obtain a green check in CS Academy. There is no partial credit on individual exercises.
• For guided exercises, watching the guided video is required -- it will show you how to solve the exercise elegantly, will save you lots of time, and will best prepare you for later exercises. Thus, first read the writeup and then carefully watch the guided video. Then and only then should you solve the guided exercise.
• Problems with a * will mostly be covered in Wednesday's recitation!
• Problems with a ** will mostly be covered in Thursday's lecture!
