Well you got the newman_conway method, but it looks like you weren't able to finish the subsequence problem. I pointed out a few things there, let me know if you have further questions.

max = nums[0]
current = nums[0]

nums.each do |index|

index here won't be an index into the array, it will be a value.

Maybe you meant:

Suggested change
nums.each do |index|
nums.length.time do |index|


raise NotImplementedError, "Method not implemented yet!"
max = nums[0]
current = nums[0]

Otherwise you will add nums[0] twice.

Suggested change
current = nums[0]
current = 0

I think you're on the right track, but not quite there yet. 😢

This works, although you could use an array just as easily as a hash here.
