Note: the % "mod" operator computes the remainder, e.g. 5 % 2 is 1. 
(a) Define a function count_odds(nums) that returns the number of 
odd ints in the given array. 
e.g.
count_odds([2, 1, 2, 3, 4]) -> 2
count_odds([2, 2, 0]) -> 0
count_odds([1, 3, 5]) -> 3

(b) Define a function count_evens_oddIndex(nums) that returns the number of 
even ints on the odd positions (i.e. with an odd index) in the given array. 

e.g.
count_evens_oddIndex([2, 1, 2, 3, 4]) -> 0
count_evens_oddIndex([2, 4, 6, 8]) -> 2
count_evens_oddIndex([2, 3, 5, 6, 8]) -> 1
