HackerRank Simple Array Sum solution

Hello Programmers, In this post, you will learn how to solve HackerRank Simple Array Sum solution. This problem is a part of the HackerRank Algorithms Series.

One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions. We are going to solve the HackerRank Algorithms problems using C, CPP, JAVA, PYTHON, JavaScript & SCALA Programming Languages.

You can practice and submit all HackerRank problem solutions in one place. Find a solution for other domains and Sub-domain. I.e.

HackerRank Simple Array Sum

Given an array of integers, find the sum of its elements.

For example, if the array ar = [1, 2, 3], 1 + 2 + 3 = 6, so return 6.

Function Description

Complete the simpleArraySum function in the editor below. It must return the sum of the array elements as an integer.

simpleArraySum has the following parameter(s):

• ar: an array of integers

Input Format

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

Constraints

• 0 < n, arr[i] <= 1000

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 arrays elements: 1+2+3+4+10+11=31

Simple Array Sum Solution in C

```#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
#define N 1000

int main() {

/* Enter your code here. Read input from STDIN. Print output to STDOUT */
int x[N],n,i,t;
scanf("%d",&n);
for(i=0;i<n;i++)
if(i==0)

{scanf("%d",&x[i]);t=x[i];}
else
if(getchar()==' ')
{scanf("%d",&x[i]);t=t+x[i];}
printf("%d",t);
return 0;```

Simple Array Sum Solution in Cpp

```#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int main() {

unsigned long long int N, Sum = 0, i, Num;

cin>>N;

for (i = 1 ; i <= N ; i++)
{
cin>> Num;
Sum += Num;
}

cout<<Sum<<endl;

/* Enter your code here. Read input from STDIN. Print output to STDOUT */
return 0;```

Simple Array Sum Solution in Java

import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int length = input.nextInt();
int sum = 0;

for(int i = 0; i < length; i++) {
sum += input.nextInt();
}

System.out.println(sum);
}```

Simple Array Sum Solution in Python

```n = input()
arr = map(int,raw_input().split())
print sum(arr)```

Simple Array Sum Solution using JavaScript

```function processData(input) {
var inputs = input.split('\n');
var arrayToSum = inputs[1].split(' ');
var sum = 0;

for (var i = 0; i < arrayToSum.length; i++) {
sum += parseInt(arrayToSum[i], 10);

}
console.log(sum);
}

process.stdin.resume();
process.stdin.setEncoding("ascii");
_input = "";
process.stdin.on("data", function (input) {
_input += input;
});

process.stdin.on("end", function () {
processData(_input);
});```

Simple Array Sum Solution in Scala

```bject Solution {

def main(args: Array[String]) {
val lines = io.Source.stdin.getLines
val sum = lines.drop(1).next.split(" ").toList.map( _.toInt ).sum
println(sum)
}```

Simple Array Sum Solution in Pascal

```(* Enter your code here. Read input from STDIN. Print output to STDOUT *)
var n, s, x: longint;
begin
s:= 0;
while n>0 do begin
inc(s,x);
dec(n);
end;
writeln(s);

end.```

FAQ:

1. How do you solve the first question in HackerRank?

If you want to solve the first question of Hackerrank then you have to decide which programing language you want to practice i.e C programming, Cpp Programing, or Java programming then you have to start with the first program HELLO WORLD.

2. How do I find my HackerRank ID?

You will receive an email from HackerRank to confirm your access to the ID. Once you have confirmed your email, the entry will show up as verified on the settings page. You will also have an option to “Make primary”. Click on that option. Read more

3. Does HackerRank detect cheating?
