More odd than even?
Return the word "odd" if the number of odd numbers is bigger than the number of even numbers. Return the word "even" otherwise.
The list {1,3,5,8,6} returns "odd" because there are 3 odds and only 2 evens.
f({1,1,1,1}) -> odd
f({1,2,3,4,5,6}) -> even
f({-1,1,-1,1,-1}) -> odd
f({1,2,101,4,-1}) -> odd
f({4,2,6,1,1}) -> even
