This code written is Js is working in vs code but in hackerrank it is showing undefined can anyone help me out...

let sum = 0; for (let i = 0; i < ar.length; i++) { // console.log(ar[i]); sum = sum + ar[i] } console.log(sum)

Here is my solution for the simpleArraySum function, you can see the video here : https://youtu.be/b7KAvErmVIw

int simpleArraySum(vector<int> ar) {
    int sum = 0;
    for(int i = 0; i < ar.size(); i++){
        sum += ar[i];
    }
    return sum;
}

Here is the solution of Simple Array sum @OGAdultWebSeries">

function simpleArraySum(ar) { let sum=0; console.log(ar.length); for(let i=0 ;i< ar.length; i++){ sum=sum + ar[i]; } return sum;

}

Here is my code:

`def simple_array_sum(arr): """ Calculates the sum of elements in an array.

Parameters:
arr (list): The input array of numbers.

Returns:
int: The sum of elements in the array.
"""
return sum(arr)

array = [1, 2, 3, 4, 5] sum_of_array = simple_array_sum(array) print("Sum of the array:", sum_of_array)

`
