Homework1 (due Wed 25-Jun at 8pm)

---

Notes:

• You must thoroughly read the syllabus and read and sign the student contract before beginning any homework assignments.
• 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.
• Because we have not discussed coding style, hw1 will not be graded for style, but you should still make an effort to write clean and well-organized code.



• We may choose to solve some homework problems in lecture. If we do, don't just copy the answer, but you may take notes if you wish.
• Lastly, remember that homework is your opportunity to build your algorithmic thinking skills and truly learn the content well. The process is more important than the result. If you rely on AI and/or just run the code tracing problems to get the answer, you will likely learn nothing while gaining a false sense of confidence, and you will be very disappointed with your writing session, quiz, and exam grades.

Required problems

• Because HW1 is not due until Wednesday 8pm, this week's writing session (in lecture on Wednesday morning) will only ask you about the homework questions from 1.3.11 and 1.3.12 (but be sure to get those sections done before Wednesday).


• 1.2.7 Code Tracing Exercises (all, 4 stars)
• 1.3.10 Code Tracing Exercises (all, 4 stars)
• 1.3.11 Guided Exercises
  • getKthDigit (1)
  • setKthDigit (1)
• 1.3.12 Section Exercises
  • leftoverPizzaSlices (1)
  • dotsOverlap (1)
  • numberOfBricks (1)
  • getGreen (2)
• 1.4.10 Code Tracing Exercises (all, 2 stars)
• 1.4.11 Guided Exercises
  • digitCount (1)
  • closestEven (1)
  • rectanglesOverlap (3)
• 1.4.12 Section Exercises
  • getGrade (1)

Bonus/Optional

Note:

• These problems are bonus and optional (you can skip them).
• They are worth up to 3 bonus points (i.e. 3% of hw1). This is very little, so it is not worth doing these just for the points. Instead, do them if you would like to challenge yourself and gain more practice.

Bonus exercises:

• 1.4.12 Section Exercises
  • areaWithinThreeLines (2 in CS Academy, worth 1 bonus points on hw1)
• 1.4.13 Honors Exercises
  • playThreeDiceYahtzee (4 in CS Academy, worth 2 bonus points on hw1)
