Background

Stealing the testdata and printing it directly to grab the best score is a serious violation. Depending on the severity, your account may be banned.

Operation “Lift the Restrictions”!

Problem Description

You are given $n$ numbers. You need to compute their sum and output it.

Input Format

The first line contains an integer $n$.

The next line contains $n$ integers separated by spaces, representing the given $n$ numbers.

Output Format

Output one number in a single line, which is the sum of the given numbers.

5
-1 2 -3 4 -5

-3

Hint

For $25\%$ of the data, $n=10^5$.

For $25\%$ of the data, $n=10^6$.

For $25\%$ of the data, $n=10^7$.

For $25\%$ of the data, $n=10^8$.

For $100\%$ of the data, all numbers are within $[-n,n]$.

The testdata guarantees that for any prefix of the sequence, the sum of this prefix fits within the storage range of a 32-bit signed integer.
