02. Shopping List

Input

You will receive an initial list with groceries separated by an exclamation mark "!".

After that, you will be receiving 4 types of commands until you receive "Go Shopping!".

"Urgent {item}" - add the item at the start of the list. If the item already exists, skip this command.
"Unnecessary {item}" - remove the item with the given name, only if it exists in the list. Otherwise, skip this command.
"Correct {oldItem} {newItem}" - if the item with the given old name exists, change its name with the new one. Otherwise, skip this command.
"Rearrange {item}" - if the grocery exists in the list, remove it from its current position and add it at the end of the list. Otherwise, skip this command.

Constraints

There won't be any duplicate items in the initial list

Output

Print the list with all the groceries, joined by ", ":

"{firstGrocery}, {secondGrocery}, … {nthGrocery}"

Ако накой разбере начина ми на решение добре ако не може да покажете свое решение на задачата.Условието е ,че искам задачата да се реши със МАСИВ а не със ЛИСТ с лист ще е елементарно.Ако някой я е решавал с МАСИВИ моля да сподели Благодаря.
