Simple Array Sum

Simple Array Sum:

Given an array of N integers, can you find the sum of its elements?

Input Format

The first line contains an integer, N , denoting the size of the array. The second line contains N space-separated integers representing the array’s elements.

Output Format

Print the sum of the array’s elements as a single integer.

Sample Input

6
1 2 3 4 10 11

Sample Output

31

Explanation

We print the sum of the array’s elements, which is: 1 + 2 + 3 + 4 + 10 + 11 = 31

Solution

Python

#!/bin/python

import sys


n = int(raw_input().strip())
arr = map(int,raw_input().strip().split(' '))
print sum(arr)

Bash

function sum {
    s=0
    for i in `seq 1 $#`; do
        s=$(($s + ${!i}))
    done
    echo $s
}

read n
read a
sum $a
