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
```python
[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)
```
def find_outlier(integers):
    listEven = []
    listOdd = []
    for n in integers:
        if n % 2 == 0:
            listEven.append(n)
        else:
            listOdd.append(n)
            
    if len(listEven) == 1:
        return listEven[0]
    else:
        return listOdd[0]
def find_outlier(integers):
    listEven = []
    listOdd = []
    for n in integers:
        if n % 2 == 0:
            listEven.append(n)
        else:
            listOdd.append(n)
            
    if len(listEven) == 1:
        return listEven[0]
    else:
        return listOdd[0]
