Baltic Olympiad in Informatics: 2010 Day 2, Problem 2
Kristian works as a shopkeeper and sells candies. There are packages in his shop and each of them may contain a different number of candies. When a customer comes and asks for candies, Kristian has to bring some packages, such that the total number of candies in those packages is equal to . If he is unable to do this, for example if someone asks for candies and there are only packages with candies in each of them, often the customer gets upset and leaves.
Because of that, Kristian wanted to know how many different options he could provide to the next customer with the packages he currently has. He managed to solve this problem and now he is wondering what to do to improve the result. He wants to open one package and change the number of candies in it so that the total number of distinct options he can offer to the customer will increase as much as possible.
Constraints
Input Specification
The first line of the text file candies.in contains one integer . The second line contains a sequence of space-separated integers , describing the numbers of candies in each package.
