I'm going with option A. Replacing line n2 with .map (n -> System.out.println (''New Price'' + n --1)) and removing line n3 should do the trick.

Haha, I bet the real answer is to just add a '+' to the 'New Price' string! Developers love their shortcuts.

But if you replace line n3 with .forEach (n -> System.out.println (''New Price'' + n)), it will print Price 5 New Price 4.

Option D seems more straightforward to me. Replacing line n3 with .forEach (n -> System.out.println (''New Price'' + n)) will directly print the new price.

I think option B is the correct answer. Replacing line n2 with .mapToInt (n -> n -- 1) will decrement each value by 1 and print the new price.

Yes, I think so too. It makes sense to decrement each value by 1 to get the new price.
