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)
Sample Tests
test.assert_equals(find_outlier([2, 4, 6, 8, 10, 3]), 3)
test.assert_equals(find_outlier([2, 4, 0, 100, 4, 11, 2602, 36]), 11)
test.assert_equals(find_outlier([160, 3, 1719, 19, 11, 13, -21]), 160)
Solution- ###Python
def find_outlier(integers):
even=[]
odd=[]
for i in integers:
if i % 2 == 0:
even.append(i)
else:
odd.append(i)
if len(even)==1:
return even[0]
else:
return odd[0]
