re: Daily Challenge #35 - Find the Outlier VIEW POST

TOP OF THREAD FULL DISCUSSION
re: I believe this would fail if the outlier is even and the rest are an odd number of odd numbers. The examples all have an even number of odd numbers...
 

It seems that I can’t make it right and as simple as it was. So I’ll stick with this solution:

def findOutlier numbers
  if numbers.first(3).count(&:even?) > 1
    numbers.find(&:odd?)
  else
    numbers.find(&:even?)
  end
end

puts findOutlier([2, 4, 0, 100, 4, 11, 2602, 36])
puts findOutlier([160, 3, 1719, 19, 11, 13, -21, 33])
puts findOutlier([160, 3, 1719, 19, 11, 13, -21])
puts findOutlier([4, 8, 15, 16, 24, 42])
puts findOutlier([16, 6, 40, 66, 68, 28])
puts findOutlier([3,3])
