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...

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。

Given an integer array nums sorted in non-decreasing order, remove the duplicates in-place such that each unique element appears only once. The relative order of the elements should be kept the same. Then return the number of unique elements in nums. Consider the number of unique elements of...
