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);
}
}

Shashank loves trees and math. He has a rooted tree, T , consisting of N nodes uniquely labeled with integers in the inclusive range [1 , N ]. The node labeled as 1 is the root node of tree , and each node in is associated with some positive integer value (all values are initially ). Let's define Fk as the Kth Fibonacci number. Shashank wants to perform 22 types of operations over his tree, T
