**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);
}
}

## Cycle Detection

A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0. Example head refers 1 -> 2 -> 3 -> NUL The numbers shown are the node numbers, not their data values. There is no cycle in this list so return 0. head refer

This challenge is part of a tutorial track by MyCodeSchool Given pointers to the head nodes of 2 linked lists that merge together at some point, find the node where the two lists merge. The merge point is where both lists point to the same node, i.e. they reference the same memory location. It is guaranteed that the two head nodes will be different, and neither will be NULL. If the lists share
