Q.

Description:
You are given an array (which will have a length of at least 3, but could be very large) containing integers. The array is either entirely comprised of odd integers or entirely comprised of even integers except for a single integer N. Write a method that takes the array as an argument and returns this "outlier" N.

Examples
[2, 4, 0, 100, 4, 11, 2602, 36]
Should return: 11 (the only odd number)

[160, 3, 1719, 19, 11, 13, -21]
Should return: 160 (the only even number)

A)

function findOutlier(integers){
  //your code here
  let odd = [];
  let even = [];
  for (let e of integers) {
    if (e%2 === 0) {
      even.push(e)
    }
    else {
      odd.push(e)
    }
  }
  return odd.length === 1 ? odd[0] : even[0]
}
