What is the original sentence?

The sentence in question is

Nebraska has floods in some years, in others drought.

I thought the original sentence is like

Nebraska has floods in some years, and it has drought in other years.

And the subject and the verb in the second sentence is omitted because it used again. But in this case, where is the conjuction, "and" gone?

Or is it participle sentence, like

Nebraska has floods in some years, in others having drought.

And 'having' is omitted. Also, is it possible to delete 'having' like this?

Always appreciate your help.

1a. Nebraska has floods in some years, in others drought.
1b. Nebraska has floods in some years and Nebraska has drought in other years.

Step 1: Delete the second Nebraska has,

EX: Nebraska has floods in some years and drought in other years.

Step 2: Delete the second years,

EX: Nebraska has floods in some years and drought in other.

Step 3: Add -s to other,

EX: Nebraska has floods in some years and drought in others.

Step 4: Relace and with a comma,

EX: Nebraska has floods in some years, drought in others.

The comma (,) represents the conjunction and.

All the best, :D
