Each candy has been labelled with an integer. The parents will get suspicious if one of the candy types goes completely missing (the candy type should not be missing before Bob received the bag).

What is the maximum number of candies Bob can eat?

#### Input Specification

The next $$N$$ lines of the input will each contain an integer ranging from $$0$$ to $$10^9$$ inclusive, indicating the type of the candy.
