I want my function to return the longest Array within a nested array (including the array itself) so
nested_ary = [[1,2],[[1,2,[[1,2,3,4,[5],6,7,11]]]],[1,[2]]
deep_max(nested_ary)
=> [1,2,3,4,[5],6,7,11]
simple_ary = [1,2,3,4,5]
deep_max(simple_ary)
=> returns: [1,2,3,4,5]
I created a function to collect all arrays. I have to get the max value in another function.
my code:
def deep_max(ary)
ary.inject([ary]) { |memo, elem|
if elem.is_a?(Array)
memo.concat(deep_max(elem))
else
memo
end }
end
This gives me what I want:
deep_max(nested_ary).max_by{ |elem| elem.size }
Is there a way to get this max inside of the function?
def deep_max(arr)
biggest_so_far = arr
arr.each do |e|
if e.is_a?(Array)
candidate = deep_max(e)
biggest_so_far = candidate if candidate.size > biggest_so_far.size
end
end
biggest_so_far
end
deep_max [[1, 2], [[1, 2, [[1, 2, 3, 4, [5], 6, 7, 11]]]], [1, [2]]]
#=> [1, 2, 3, 4, [5], 6, 7, 11]
