08. Browser History Upgrade (Stacks & Queues - Lab)

Здрайвейте!

Опитвам се да реша осма задача от лекцията за стекове и опашки, но не мога да стигна до решение, по-добро от 50/100 в Judge. frown
Моля за насоки къде бъркам

Благодаря предварително!

Кодът ми: клик.

Условие:

8. Browser History Upgrade

Extend "Browser History" with a "forward" instruction which visits URLs that were navigated away from by "back". Each forward instruction visits the next most-recent such URL. If a normal navigation happens, all potential forward URLs are removed until a new back instruction is given If the forward instruction can’t be executed, print "no next URLs".

Hints

  • Use the solution from Browser History
  • Use ArrayDequeue<> as queue to keep the forward pages
  • Use clear() method to reset the forward pages
  • Use addFirst() when adding page to the forward pages

Examples
