How this page works
The writing boxes below are yours. What you type stays in this browser, is saved here as you go, and is never sent to us or to your teacher. Hand the written work in the way your teacher asked for it.
The graded check at the bottom is the part that records to your teacher's gradebook.
Part B, from your handoutNot recorded
Your handout says these are the same items available here. Part A stays on paper.
Q1 · 3 points on the handout
Write your own four-line pseudocode sequence that creates a list of three song titles (strings) and then DISPLAYs the SECOND title. State exactly what prints, and show you used the exam sheet's 1-indexed rule.
Q2 · 3 points on the handout
Each element of the songs list above is itself a string. Explain what makes "Signal" a string, and why "Signal" and "Signl" - or "Signal" and "signaL" - count as different strings.
Q3 · 2 points on the handout
ENRICHMENT: The temps list let five readings be treated as one value under one name. Other languages call this an array. In one or two sentences, explain the phrase 'treated as a single value,' and note what the CED explicitly says is OUTSIDE the scope of this course.

Next step: you traced this list by hand. Now head to the Topic 3.2 page and type and run the harder versions, where the computer checks your output for you.

About the line in your handout
Your handout says this exercise is available online and auto-graded. The exercise IS here, and it is the same work in the same order, but the auto-graded half is not written for this topic yet. Nothing on this page is scored or sent to your teacher.
Hand this in the way your teacher asked for it. Topic 1.1 has its graded check today, and the rest follow.
