Question

For the algorithm below:

for (each word in the file)

if word == "happy"

return TRUE

read next word

return FALSE

What is the best case?

What is the time complexity for the best case?

What is the worst case?

What is the time complexity for the worst case?

Please answer the above questions by marking your answer with the number for each subquestion.

Answer 1

Sure, here are the answers to your questions:

Best case: The best case scenario is when the word "happy" is the first word in the file. In this case, the algorithm will return TRUE immediately, and the time complexity will be O(1).

Time complexity for the best case: O(1)

Worst case: The worst case scenario is when the word "happy" does not appear in the file at all. In this case, the algorithm will read through the entire file, and the time complexity will be O(n), where n is the number of words in the file.

Time complexity for the worst case: O(n)

Answers:

The best case is when the word "happy" is the first word in the file. The time complexity for the best case is O(1). The worst case is when the word "happy" does not appear in the file at all. The time complexity for the worst case is O(n).
