Count Distinct Designations

You are given a list of employee designations. Your task is to count the number of distinct designations. The comparison is case sensitive; for instance, 'Manager' and 'manager' are considered different designations.

Formally, you are given an integer \(N\) and a sequence of \(N\) strings. You need to output the number of unique designations in the sequence.

Example: For \(N = 7\) and designations ["Manager", "Engineer", "Executive", "Manager", "Designer", "Engineer", "Intern"], the distinct designations are {"Manager", "Engineer", "Executive", "Designer", "Intern"} so the answer is 5.
