Searching Algorithms Quiz

What is a common task for computer algorithms when searching for information?

• Sorting data

• Searching based on a given criterion

• Calculating averages

• Encrypting data

What does a binary search require the data to be?

• Unordered

• In a tree structure

• Ordered or sorted

• In a graph structure

In a binary search, what is the first step when looking for a specific value?

• Compare with the first element

• Compare with the middle or median value

• Compare with the last element

• Compare with a random element

What is the key point about binary search mentioned in the document?

• It is faster than linear search

• It cannot be carried out unless the data is in order

• It is the simplest search method

• It works best with small data sets

What is a disadvantage of linear search with large data sets?

• It is very fast

• It is very slow

• It requires sorting

• It uses too much memory

What is the final step in a binary search when the value is found?

• Stop the search

• Continue searching

• Restart the search

• Sort the data

What is the main advantage of binary search over linear search?

• It is simpler

• It is faster with ordered data

• It requires less memory
