Sum of integers in a list (recursive).

This technical problem deals with finding the sum of all integers in a list using recursion. An example input is given, along with the expected output.


Given a list of integers, write a recursive function to find the sum of all the integers in the list.
Example input: [1, 2, 3, 4, 5]
Example output: 15


This solution is in JavaScript. Our A.I. can create solutions in multiple languages.

// Solution:

function sum(arr) {
  if (arr.length === 0) {
    return 0;
  return arr[0] + sum(arr.slice(1));

// This solution is optimal because it is a linear solution. It is linear because the number of operations is directly proportional to the size of the input.

A.I. Evaluation of the Solution

This solution is correct and demonstrates a good understanding of recursion. The approach is clear and concise.
