问题: 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…

一.题目描写叙述 二.解题技巧 这道题和Remove Duplicates from Sorted Array这道题是相似的.仅仅只是这里同意出现反复的数字而已,能够採用二分搜索的变种算法.仅仅只是增加了剔除和第一个元素同样的元素的过程. 还有一个思路是增加一个变量.用于记录元素出现的次数.这题由于是已经排序的数组,所以一个变量就可以解决.假设是没有排序的数组,则须要引入一个hash表来记录出现次数. 三.演示样例代码 #include <iostream> #include <vect…

题目: Follow up for "Remove Duplicates":What if duplicates are allowed at most twice? For example,Given sorted array A = [1,1,1,2,2,3], Your function should return length = 5, and A is now [1,1,2,2,3]. 说明: 1)设个标志可实现 实现: class Solution { public: in…

题目难度:Easy 题目: 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 by modifying the input array in-place with O(1) extr…

Follow up for "Remove Duplicates":What if duplicates are allowed at most twice? For example,Given sorted array nums = [1,1,1,2,2,3], Your function should return length = 5, with the first five elements of nums being 1, 1, 2, 2 and 3. It doesn't…

题目: 删除排序数组中的重复数字 II 跟进“删除重复数字”: 如果可以允许出现两次重复将如何处理? 样例 给出数组A =[1,1,1,2,2,3],你的函数应该返回长度5,此时A=[1,1,2,2,3] 解题: 在这里看到的 与上一题方法很类似,这里保存相同元素长度小于2的保存在原来的数组中 很巧妙 Java程序: public class Solution { /** * @param A: a array of integers * @return : return an integer…
