Linear Search Algorithm Quiz

What is the primary advantage of using a linear search on small data sets?

• It requires the data to be sorted.

• It uses less memory than other algorithms.

• It is the fastest algorithm available.

• It is simple to implement.

In a linear search, what is the initial value of the 'found' variable?

• Undefined

• Null

• True

• False

What does the while loop in the linear search pseudo code check for?

• If the list is empty

• If the list contains duplicates

• If the item is found or the end of the list is reached

• If the list is sorted

In the Python example, what happens when the item is found in the list?

• The loop continues to check all items.

• The 'found' variable is set to false.

• The loop exits after setting 'found' to true.

• The index is reset to zero.

Why might different implementations of the linear search algorithm exist?

• Because pseudocode has a fixed syntax.

• Because different implementations are incorrect.

• Due to variations in programming languages.

• Because there is only one correct way to implement it.

What is a key criterion for an algorithm to be considered correct?

• It must use the least amount of memory.

• It must be written in Python.

• It must produce the correct result for all inputs.

• It must be the fastest algorithm.

What change can be made to the while loop condition to simplify the code?

• Replace 'found = false' with 'not found'

• Use a for loop instead of a while loop

• Add a break statement

• Remove the index variable

What is a potential limitation of the linear search implementation discussed?

• It crashes if the item is not found.

• It only finds the first occurrence of an item.

• It cannot find any items in the list.

• It requires the list to be sorted.

What additional resource is mentioned for further learning about algorithms?

• An online course

• A YouTube channel

• A book available on Amazon

• A software tool

What should you do when coding an algorithm in an exam?

• Use the exact code from the textbook

• Ensure the algorithm is efficient and clear

• Write the code in multiple languages

• Ignore the question details
