CountposSumNeg.js

/*Instructions/Task: Given an array of integers.

Return an array, where the first element is the count of positives numbers and the second element is sum of negative numbers. 0 is neither positive nor negative.

If the input is an empty array or is null, return an empty array.

Example
For input [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, -11, -12, -13, -14, -15], you should return [10, -65].*/

//My Answer
function countPositivesSumNegatives(input) {
  if (input === null || input.length === 0) {
    return [];
  }
  let countPositives = 0;
  let sumNegatives = 0;

  for (let num of input) {
    //     num = arr[i];
    if (num > 0) {
      countPositives++;
    } else if (num < 0) {
      sumNegatives += num;
    }
  }
  return [countPositives, sumNegatives];
}

// // Example usage:
const inputArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, -11, -12, -13, -14, -15];
const result = countPositivesSumNegatives(inputArray);
console.log(result);
