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.

My Solution:

<?php

    $handle = fopen ( "php://stdin","r" );
    fscanf( $handle, "%d", $n );
    $arr_temp = fgets( $handle );
    $numbers = explode( " ", $arr_temp);
    $sum = intval( array_sum( $numbers ) );

    echo $sum;

    fclose( $handle );

?>
