题目内容 本题来源LeetCode 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,…

题目内容 本题来源于LeetCode 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, Giv…

这是悦乐书的第149次更新,第151篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第8题(顺位题号是26).给定一个已经排序(由小到大)的整数数组(元素可以重复),计算其中不重复元素的个数n,并将数组的前n个元素依次赋值为筛选后的不重复元素.不许使用新数组接收数据.例如: nums = {1,1,2} 输出不重复元素的个数为2 数组前2个元素为1和2,即nums = {1,2,2} 本次解题使用的开发工具是eclipse,jdk使用的版本是1.8,环境是win7 6…

描述 Follow up for "Remove Duplicates": What if duplicates are allowed at most twice? 示例 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 matte…

Remove Duplicates from Sorted Array II 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].     用两个指针,…

Remove Duplicates from Sorted Array 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.…

以下三个问题的典型的两个指针处理数组的问题,一个指针用于遍历,一个指针用于指向当前处理到位置 一:Remove Element Given an array and a value, remove all instances of that value in place and return the new length. The order of elements can be changed. It doesn't matter what you leave beyond the new l…

LeetCode 80 Remove Duplicates from Sorted Array II [Array/auto] <c++> 给出排序好的一维数组,如果一个元素重复出现的次数大于两次,删除多余的复制,返回删除后数组长度,要求不另开内存空间. C++ 献上自己丑陋无比的代码.相当于自己实现一个带计数器的unique函数 class Solution { public: int removeDuplicates(std::vector<int>& nums) {…

Remove Duplicates from Sorted Array II 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]. 解法一: 我是Pic…

排序数组去重题,保留重复两个次数以内的元素,不申请新的空间. 解法一: 因为已经排好序,所以出现重复的话只能是连续着,所以利用个变量存储出现次数,借此判断. Runtime: 20 ms, faster than 19.12% of C++ online submissions for Remove Duplicates from Sorted Array II. class Solution{public:  int removeDuplicates(vector<int> &num…
