Question

What is a time complexity for finding all the maximal palindrome in a string?

(a) Ɵ (n)

(b) Ɵ (n!)

(c) Ɵ (1)

(d) O (log n!)

Question is from Suffix tree in chapter Trie of Data Structures & Algorithms I

I have been asked this question in examination.

Answer 1

Correct choice is (a) Ɵ (n)

The explanation is: Palindrome is a string that is the same when reading forward as well as backward. To check if a substring is present in a string of a length of n, the time complexity for such operation is found to be O (n). The time complexity for finding all the maximal palindrome in a string is Ɵ (n).
