# A Very Big Sum

### Problem Statement :

```In this challenge, you are required to 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):

int ar[n]: an array of integers .

Return

long: the sum of all array elements

Input Format

The first line of the input consists of an integer n/
.
The next line contains n space-separated integers contained in the array.

Output Format

Return the integer sum of the elements in the array.

Constraints
1 <= n <=10
0 <= ar[i] <= 10^10```

### Solution :

```                            ```Solution in C :

In C :

long aVeryBigSum(int ar_count, long* ar) {
long double sum = 0;
for(int i = 0; i< ar_count; i++)
{
sum = sum + ar[i];
}

return sum;

}

In C ++ :

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

int main() {
int n;
cin>>n;
unsigned long long int sum=0,in;
for(int i=0;i<n;i++)
{cin>>in;
sum+=in;}
cout<<sum;
return 0;
}

In Python :

input()
print(sum(map(int, input().split())))

In Java :

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

public class Solution {

public static void main(String[] args) {
Scanner s = new Scanner(System.in);
int t = s.nextInt();
long sum = 0;
while(t-- > 0){
sum += s.nextInt();
}
System.out.println(sum);
}
}```
```

## No Prefix Set

There is a given list of strings where each string contains only lowercase letters from a - j, inclusive. The set of strings is said to be a GOOD SET if no string is a prefix of another string. In this case, print GOOD SET. Otherwise, print BAD SET on the first line followed by the string being checked. Note If two strings are identical, they are prefixes of each other. Function Descriptio

## Cube Summation

You are given a 3-D Matrix in which each block contains 0 initially. The first block is defined by the coordinate (1,1,1) and the last block is defined by the coordinate (N,N,N). There are two types of queries. UPDATE x y z W updates the value of block (x,y,z) to W. QUERY x1 y1 z1 x2 y2 z2 calculates the sum of the value of blocks whose x coordinate is between x1 and x2 (inclusive), y coor

## Direct Connections

Enter-View ( EV ) is a linear, street-like country. By linear, we mean all the cities of the country are placed on a single straight line - the x -axis. Thus every city's position can be defined by a single coordinate, xi, the distance from the left borderline of the country. You can treat all cities as single points. Unfortunately, the dictator of telecommunication of EV (Mr. S. Treat Jr.) do

## Subsequence Weighting

A subsequence of a sequence is a sequence which is obtained by deleting zero or more elements from the sequence. You are given a sequence A in which every element is a pair of integers i.e A = [(a1, w1), (a2, w2),..., (aN, wN)]. For a subseqence B = [(b1, v1), (b2, v2), ...., (bM, vM)] of the given sequence : We call it increasing if for every i (1 <= i < M ) , bi < bi+1. Weight(B) =
