A celebrity is defined as someone who is known by everyone but does not know anyone. The celebrity problem is to identify the celebrity, if one exists, in a group of n persons by asking questions only of one form, "Excuse me, do you know the person over there?". Write an algorithm in a pseudocode to solve the celebrity problem. You may represent a question as a function call KNOW(i, j) which returns "Yes" if person i knows person j, "No" otherwise. To obtain points for this question, your algorithm must find a celebrity or decide none exists by asking at most O(n) questions. How the data will be represented in your algorithm
