Calculate and print the sum of the elements in an array, keeping in mind that some of those integers may be quite large.
Function Description:
Complete the aVeryBigSum function in the editor below. It must return the sum of all array elements.
aVeryBigSum has the following parameter(s):
ar: an array of integers.
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.
My Solution:
'use strict';
const fs = require('fs');
process.stdin.resume();
process.stdin.setEncoding('utf-8');
let inputString = '';
let currentLine = 0;
process.stdin.on('data', inputStdin => {
inputString += inputStdin;
});
process.stdin.on('end', _ => {
inputString = inputString.replace(/\s*$/, '')
.split('\n')
.map(str => str.replace(/\s*$/, ''));
main();
});
function readLine() {
return inputString[currentLine++];
}
function aVeryBigSum(ar) {
var sum=0;
for(let i=0;i<ar.length;i++){
sum = sum + ar[i];
}
return sum;
}
function main() {
const ws = fs.createWriteStream(process.env.OUTPUT_PATH);
const arCount = parseInt(readLine(), 10);
const ar = readLine().split(' ').map(arTemp => parseInt(arTemp, 10));
let result = aVeryBigSum(ar);
ws.write(result + "\n");
ws.end();
}
