Write a function that groups nodes with the same value in a linked list.

The code you will write will rearrange all duplicate values $$in the list sequentially side by side.

should be regulated. For example, let's say the number $"3"$ repeats four times in the list. In this case first

Other repeating numbers $"3"$ should appear right next to the number $"3"$ encountered. So the list is first

will be in the same order as the situation.

The function you will write will have $2$ parameters: A Node pointer that represents the head of the linked list.

max$\_$repeats for reference and maximum number to combine. Other with the same value

values $$should be deleted.
