Algorithm Specification

Question 1

What is the algorithm used when designing software known as?

Answer 1

Pseudocode

Question 2

What does an array store?

Answer 2

A list of data all of which are the same type

Question 3

What is the purpose of input validation?

Answer 3

To ensure that software is robust by repeatedly asking for input data and rejecting invalid data until restrictions imposed by the software are met

Question 4

How does finding maximum/minimum work?

Answer 4

Sets an initial value to the first item in an array and then compares it to the remaining items

Question 5

How does counting occurrences work?

Answer 5

Sets a total to 0 at the beginning and increases the value as items are found to match the search item

Question 6

How does linear search work?

Answer 6

Sets a Boolean variable to false initially and uses a conditional loop to set it to true when a specific item is found.
Loop is terminated when item is found or the end of the array is reached.

Question 7

The linear search algorithm uses…

Answer 7

A conditional loop and a Boolean variable

Question 8

The counting occurrences algorithm uses…

Answer 8

A fixed loop

Question 9

What is an index?

Answer 9

The position in an array

Question 10

Why are meaningful identifiers important when creating an algorithm?

Answer 10

So that programmers can understand and convert the algorithm to the corresponding high level language of their choosing

Question 11

What is an algorithm?

Answer 11

Applied to structure the solution to a problem by a programmer while applying problem solving and computational thinking skills
