Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this in place with constant memory. For example, Given input array A = [1,1,2], Your function should retur...

We sort the array in the first step, which takes O(NlogN) time. After that, we execute the loop from 1 to n-1, which requires O(N) time. Therefore, this method’s worst-case time complexity for eliminating duplicates from the array is O(NlogN)+O(N)=O(NlogN). Auxiliary Space ...

26. Remove Duplicates from Sorted Array 给定一个有序的数组nums,删除重复内容,使每个元素只出现一次并返回新的长度。 不要为其他数组分配额外空间,您必须通过在O(1)额外内存中就地修改输入数组来实现此目的。 思路:数组有序,重复数组必定相邻! 其它和27是一样的。
