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 nums = [1,1,2], Your function should re...

https://leetcode.com/problems/remove-duplicates-from-sorted-array/ 题意分析: 给定一个排好序的数组,去除重复的数,返回新数组的长度,不能申请额外的空间,超过新数组长度部分是什么数都无所谓。 题目思路: 这是一个很简单的题目,由于给定的数组已经排序,那么用i,j两个下标,i记录新数组的下标,j是原来数组下...
