Algorithm design (planning solutions) in Intro to Computing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the algorithm by defining the first step.

Intro to Computing

step1 = "[1]"

Drag options to blanks, or click blank then click option'

ARun the program

BWrite the code

CIdentify the problem

DTest the output

Attempts:

3 left

💡 Hint

Common Mistakes

Starting with writing code before understanding the problem

Trying to test output without a plan

The first step in algorithm design is to identify the problem clearly before planning a solution.

2fill in blank

medium

Complete the code to represent the step where you plan the solution.

Intro to Computing

step2 = "[1]"

Drag options to blanks, or click blank then click option'

ADesign the algorithm

BRun the program

CDebug the code

DIdentify the problem

Attempts:

3 left

💡 Hint

Common Mistakes

Skipping the design and jumping to coding

Confusing debugging with planning

After identifying the problem, the next step is to design the algorithm, which means planning the steps to solve the problem.

3fill in blank

hard

Fix the error in the code to correctly represent the step where you check the algorithm.

Intro to Computing

step3 = "[1]"

Drag options to blanks, or click blank then click option'

ATest the algorithm

BWrite the code

CIdentify the problem

DIgnore errors

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing testing with writing code

Ignoring errors during planning

Testing the algorithm means checking if the planned steps work correctly before coding.

4fill in blank

hard

Fill both blanks to complete the algorithm design steps in order.

Intro to Computing

steps = ["[1]", "[2]"]

Drag options to blanks, or click blank then click option'

AIdentify the problem

BWrite the code

CDesign the algorithm

DTest the algorithm

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing the order of steps

Starting with coding before planning

The correct order starts with identifying the problem, then designing the algorithm as the plan.

5fill in blank

hard

Fill all three blanks to complete the main steps of algorithm design.

Intro to Computing

algorithm_steps = ["[1]", "[2]", "[3]"]

Drag options to blanks, or click blank then click option'

AIdentify the problem

BDesign the algorithm

CTest the algorithm

DRun the program

Attempts:

3 left

💡 Hint

Common Mistakes

Skipping testing

Running the program before testing the algorithm

The main steps are: identify the problem, design the algorithm, then test the algorithm before running code.
