Question

PLEASE WRITE IN C#

Problem: Summing up sums.

For this question, you’ll understand the importance of using the results of smaller sets of work. You’re going to create a recursive function that takes in an array of random integers and returns a “sum of sums”. This is best explained through an example. If you have 5 elements in an array, the function should return the sum of elements 0-4, 1-4, 2-4, 3-4, and 4.   So, if we had an array of:

5, 18, 4, 7, 11

The sum of sums would be (45+40+22+18+11) = 136. Hint: is the sum of sums not just the sum of the current array + the sum of sums of an array?

Example Output using {5, 18, 4, 7, 11}:

136

Example Output using {50, 19, 1, -49, 3, 99, 3, 21, 63}:

1260

Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

using System;
class HelloWorld {
public static int sumOfSums(int[] arr, int k) {

if (k == 0) {

return arr[0];

}

return arr[k] * (k + 1) + sumOfSums(arr, k-1);

}
static void Main() {
int[] arr = {5, 18, 4, 7, 11};
Console.WriteLine(sumOfSums(arr, arr.Length - 1));
int[] arr1 = {50, 19, 1, -49, 3, 99, 3, 21, 63};
Console.WriteLine(sumOfSums(arr1, arr1.Length - 1));

}
}
