When is a binary search faster than a linear search?

When there is a large amount of data

When there is a small amount of data

Which one of the following is an advantage of a linear search?

It is a simple algorithm to write.

It takes a long time to find the item.

It is more efficient than a binary search.

It is a complex algorithm to write.

Which of the following descriptions best describes a linear search:

Elements do not need to be in order, check each item in turn.

Put the elements in order, check each item in turn

Put the elements in order, compare with the middle value, split the list in order and repeat

Elements do not need to be in order, compare to the middle value, split the list in order and repeat.

Which of the following best describes a binary search:

Put the elements in order, compare with the middle value, split the list in order and repeat

Put the elements in order, check each item in turn.

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.

What is a disadvantage of using selection sort?

It will not exit early if the entire list is already ordered in an early pass.

There are some cases in which the list will not be sorted.

It uses a divide-and-conquer approach.

What is an advantage of a linear search?

It only works with ordered lists

What does a binary search do?

Takes the data and splits it in half repeatedly until it finds the data item requested

Looks at the first item of data, then each one in turn, until it finds the data item requested

Converts all the data into binary

Which search algorithm would be best to use with ordered data?

Either binary search or a linear search

What is an advantage of a binary search

It only works with ordered lists

What is the biggest disadvantage of a binary search?

It can only be used if the data is sorted into an order

It takes the data and keeps dividing it in half until it finds the item it is looking for

What is a Binary Search?

An algorithm to search ordered data

An algorithm to search unordered data

A method of sorting data by dividing a list into two sub-lists and then repeating the process until all elements are in order.

A method of sorting data by inserting each element into the correct order.

What is a Linear Search?

An algorithm to search unordered data

An algorithm to search ordered data

A method of sorting data by dividing a list into two sub-lists and then repeating the process until all elements are in order.

A method of sorting data by inserting each element into the correct order.

Can you use a Binary Search on the following list [12, 11, 9, 8, 4, 5, 3, 10]

No, because the data is not in order.

Yes, you can perform a Binary Search on any list.

Yes, because it is the simplest search algorithm.

No, because the data is numeric.
