Review of Big Idea 3

What is an element in the context of a list?

• A method of sorting

• A random number

• An individual value in a list that is assigned a unique index

• A type of data structure

What is an index used for in a list or string?

• To store data

• To reference elements

• To delete elements

• To sort elements

What is one of the main benefits of data abstraction in programming?

• It increases the complexity of the program.

• It manages complexity by naming a collection of data without specific details.

• It makes the program run faster.

• It reduces the need for data storage.

How can data abstraction be created in programming?

• Using variables

• Using loops

• Using lists

• Using functions

What happens if an index is less than one or greater than the list length when using a list?

• The program will continue running.

• The list will automatically adjust its size.

• An error message is produced and the program will terminate.

• The index will reset to zero.

What is an algorithm?

• A random set of instructions

• A finite set of instructions that accomplish a specific task

• An infinite loop of commands

• A single command to perform a task

What does string concatenation do?

• Splits a string into parts

• Joins two or more strings to make a new string

• Converts a string to uppercase

• Finds the length of a string

What is a substring?

• A string with no characters

• A part of an existing string

• A string that repeats

• A string with special characters

What does selection determine in an algorithm?

• The speed of execution

• Which parts of an algorithm are executed based on a condition being true or false

• The memory usage of the algorithm

• The number of variables used

What are nested conditional statements?

• Conditional statements that are repeated

• Conditional statements within conditional statements

• Conditional statements that are executed last

• Conditional statements that are ignored
