Computational Thinking & Searching Algorithm

Identify the search algorithm 

• Random search   
• Binary search
• Denary search 
• Next Item search

Identify the description of a linear search 

• Put the elements in order, check each item in turn
• Put the elements in order, compare to the middle value, split the list in order and repeat
• Elements do not need to be in order, check each item in turn
• Elements do not need to be in order, compare to the middle value, split the list in orderand repeat

Identify the description of a binary search

• Put the elements in order, check each item in turn
• Put the elements in order, compare to the middle value, split the list in order and repeat
• Elements do not need to be in order, check each item in turn
• Elements do not need to be in order, compare to the middle value, split the list in order and repeat

Define the term computational thinking

• Using a computer
• Developing an algorithm to solve a problem
• Making a computer use artificial intelligence
• Google is computational thinking

Which of the following is not a component of computational thinking?

• Abstraction
• Typing
• Decomposition
• Algorithmic thinking

Define the term abstraction within computational thinking 

• Adding together numbers
• Taking a real world problem and designing a computer program that exactly replicates every part of that problem in the computer
• Performing multiple calculations on a list of variables
• Representing real world problems in a computer program, using symbols and removing unnecessary elements

Define the term decomposition within computational thinking

• The breaking down of a program until it no longer exists
• The creation of music that can be played on a computer
• The breaking down of a problem into smaller problems
• The breaking down of waste to make compost

Identify which statement describes algorithmic thinking 

• Thinking like a computer
• Writing binary numbers 
• Identifying the steps involved in solving a problem 
• Identifying what problems need to be solved 

A linear search is to be performed on the list above, how many comparisons would it take to find the number 1? 

• 1
• 2
• 3
• 4

A binary search is to be performed on the above, how many comparisons would it take to find the number 9?   

• 0-1 
• 2-3
• 4-5
• It can't find the number 9
