Rar the Cat wants to play with a piece of string, but his string is special. As with the tradition of the Nation of Insanity (NOI), all strings are made of numbers! (We did say insanity)
Not knowing the average of the string of numbers you're playing with isn't fun. But Rar's intense focus on murdering the string has made him unable to do any calculations.
Help Rar find the average of all the numbers! (There may be decimals, just ignore them. int will do that for you automatically)
The first line of input containes an integer, N, that denotes the length of the string of numbers.
This is followed by N integers, the ith integer being the ith number on Rar's string.
A single number, the average of the number on the string
0 ≤ N ≤ 1000
The sum of all numbers will fit into a 32-bit signed integer.
