Stack and Queues Browser History Upgrade
Здравейте, може ли някой да погледне тези два кода и да ми кажа, защо с единия взимам 100/100 а с другия 50/100, пропускам нещо.

Условие:
1.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 ArrayDequeue<> as queue to keep the forward pages
