Bob Smith has to tour New Zealand visiting his company's customers. His database churns out a list of the towns where each customer lives, but it has not been well programmed so may display a given town more than once. Your job is to help Bob by removing the duplicates and telling him how many towns he actually has to visit.
Input consists of a number of lists, each representing a week of visits. The first line of each week is a single integer, N (1 < N <= 100), which is the number of towns in the list. Input is terminated by N = 0 – this week should not be processed.
Each week contains a list of N towns, each on a line by itself. The name of a town may contain more than one word. The first letter of each word in a town's name begins with an upper case letter; all other letters are lower case. A town's name will contain no more than 20 characters.
Output consists of a single line for each week. It contains the word Week, followed by a space, followed by the week number, the first week being 1, followed by a space, followed by the actual number of towns to be visited, duplicates having been removed.
