Test 1

Question 1

What are the pillars of computational thinking?

Answer 1

Problem decomposition, pattern recognition, abstraction, algorithm

Question 2

What is abstraction?

Answer 2

The process that involves identifying characteristics of a problem that can be ignored when approaching a problem.

Question 3

What kind of patterns are we looking for in pattern recognition?

Answer 3

Similar within problems
Similarities between/across problems

Question 4

Why should you engage in problem decomposition?

Answer 4

Because it allows form more flexible solutions
Because it allows for interim progress when implementing solutions
Because two smaller problems are simpler to solve then one big one

Question 5

Why do we write algorithm in a flowchart or pseudocode?

Answer 5

Allows us to see if we missed any patterns.
Allows us to evaluate any potential issues with your logic.
Allows us to visualize and plan the steps of an algorithm including inputs, outputs and loops.

Question 6

What is pattern recognition?

Answer 6

The process of identifying similarities or repetitions that can lead you to a potential solution.

Question 7

What flowchart shape would you use to indicate a decision point?

Answer 7

Diamond

Question 8

What flowchart shape would you use to indicate the beginning or end of a program?

Answer 8

Oval

Question 9

Flowchart:

Answer 9

Start  parallelogram (INPUT x;y)  Rectangle (sum = x + y)  Diamond (Is sum > 0?)  Parallelogram (OUTPUT: Sum is positive)  Parallelogram (OUTPUT: Sum is negative)

Answer 13

SubTotal, __subtotal, sub_total

Question 14

Which of the following are illegal variable names?

Answer 14

Sub-total, 34subtotal, sub/total

Question 15

Which of the following are arithmetic operators?

Answer 15

+, %, *, //

Question 16

What is //

Answer 16

In Python, you use the double slash // operator to perform floor division. This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number)
