bigSum.js

// 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 .
// The next line contains  space-separated integers contained in the array.

// Output Format

// Return the integer sum of the elements in the array.

// Constraints


// Sample Input

// 5
// 1000000001 1000000002 1000000003 1000000004 1000000005
// Output

// 5000000015
// Note:

// The range of the 32-bit integer is .
// When we add several integer values, the resulting sum might exceed the above range. You might need to use long int C/C++/Java to store such sums.
