Algorithm Quiz

What is the main feature of the insertion sort algorithm?

• It is only useful for large data sets

• It inserts each item into its correct position one at a time

• It sorts items in descending order

• It is usually replaced by less efficient sorting algorithms

When is the insertion sort algorithm particularly useful?

• For sorting items in random order

• For inserting items into already sorted lists

• For sorting large data sets

• For removing items from a data set

What is the purpose of the WHILE loop in the insertion sort algorithm?

• To check if the list is empty

• To compare items and insert them into the correct position

• To run the algorithm for a specific number of times

• To check if the current item is the smallest in the list

What is the role of the FOR loop in the insertion sort algorithm?

• To swap items in the list

• To remove items from the list

• To insert items into the correct position

• To check every item in the list

What is the purpose of the book 'Essential Algorithms for A Level Computer Science'?

• To cover every algorithm required for GCSE and A Level Computer Science

• To present actual code written in Python and Visual Basic

• To illustrate algorithms in the form of diagrams

• To provide high-level perspectives on algorithms

What is the main goal of the chapters in the book 'Essential Algorithms for A Level Computer Science'?

What is the purpose of the GCSE specification in relation to algorithms?

• To focus on the efficiency of sorting algorithms

• To provide examples of algorithms in Python and Visual Basic
