Given an array of integers, can you find the sum of its elements?
The first line contains an integer, , denoting the size of the array.
The second line contains space-separated integers representing the array’s elements.
Print the sum of the array’s elements as a single integer.
6 1 2 3 4 10 11
We print the sum of the array’s elements, which is: .
<?php $handle = fopen ("php://stdin","r"); fscanf($handle,"%d",$n); $arr_temp = fgets($handle); $arr = explode(" ",$arr_temp); array_walk($arr,'intval'); echo array_sum($arr); ?>
