A Very Big Sum

Calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large.

Input Format

The first line of the input consists of an integer . 
The next line contains  space-separated integers contained in the array.

Output Format

Print the integer sum of the elements in the array.

Constraints 
 

Sample Input

5
1000000001 1000000002 1000000003 1000000004 1000000005

Output

5000000015

Note:

The range of the 32-bit integer is .

When we add several integer values, the resulting sum might exceed the above range. You might need to use long long int in C/C++ or long data type in Java to store such sums.

Solution:

Python Code

import sys

def aVeryBigSum(n, ar):
    # Complete this function
    total = 0
    for i in range(n):
        total = total + ar[i]
    return total
n = int(input().strip())
ar = list(map(int, input().strip().split(' ')))
result = aVeryBigSum(n, ar)
print(result)
