Follow up for "Remove duplicates":What if duplicates is allowed at the most twice?For example,Given sorted array nums = [1,1,1,2,2,3] ,Your function should return length =, with the first 5 five elements of nums being 1 , 1 2 2 ,, and 3 . It doesn ' t matter what are you leave beyond the new length.Problem Solving Ideas:There are many ways to do this, and here is another way to open an array, Java implement

Slow.next2. Dummy head application: Dummy Head is we create a new node, and then let the original head node to the back of the new node. I think using the dummy head with three more obvious benefits.One is to minimize the changes to the original linked list, if the head = Head.next Such a method, head will move, so change the original situation, not very good.Two benefits are convenient to return, directly return to Dummy.next can be.Three is not the right to do special treatment, if the deleti

In Java, if you call the Remove method in ArrayList, which essentially compares the object to remove with each object in the list, the method of comparison is to call the Equals method in object, essentially comparing the memory addresses of 2 objects. As the following code: we want to delete an employee object, so we are new to the original employee object conte
