java list remove duplicates

Given a sorted array, remove the duplicates in place such, all element appear only once and return the new L Ength.Do the allocate extra space for another array, and you must does this on place with constant memory.For example,Given input array nums = [1,1,2] ,Your function should return length = 2 , with the first of the elements of nums being and 1 2 Respectivel Y. It doesn ' t matter what are you leave b

Three common techniques for Excel to remove duplicates In other scenarios, users may want to find and remove duplicates that are the same but not completely duplicated in a few fields, such as the contents of the "Name" field in line 7th and row 12th in the following figure, but the contents of the other fields are

Given A linked list, remove the nth node from the end of the list and return its head.For example, n = 2. After removing the second node from the end, the linked list becomes 1->2->3->5.Note:Given n would always be valid.Try to do the in one pass.Subscribe to see which companies asked this question/*** Definition f
