Linear Search Algorithm Quiz

What is a key characteristic of the linear search algorithm?

• It only works with numerical data.

• It is the most efficient algorithm for large datasets.

• It checks each item in the dataset sequentially.

• It requires the dataset to be sorted.

Why is linear search considered inefficient for large datasets?

• It can only be used with sorted data.

• It is difficult to implement.

• It requires additional memory.

• It has a high time complexity for large datasets.

In the word search example, what is the first step in using a linear search?

• Sort the grid alphabetically.

• Start at the last letter of the grid.

• Look for the word in reverse order.

• Begin at the first letter and move sequentially.

What is the purpose of the 'index' variable in the linear search pseudocode?

• To keep track of the current position in the array.

• To store the result of the search.

• To store the item being searched for.

• To count the number of items in the array.

What does the 'found' variable represent in the pseudocode?

• The index of the last item checked.

• Whether the search has reached the end of the array.

• If the item has been found in the array.

• The total number of items in the array.

What happens if the item is found during the linear search?

• The 'index' variable is reset to zero.

• The 'found' variable is set to false.

• A message is returned indicating the item was found.

• The search continues to the end of the array.

What is the role of the while loop in the linear search pseudocode?

• To check if the array is empty.

• To sort the array before searching.

• To iterate through the array until the item is found or the end is reached.

• To initialize the search variables.

What additional resources are mentioned for learning more about algorithms?
