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…

LeetCode 26 Remove Duplicates from Sorted Array [Array/std::distance/std::unique] <c++> 给出排序好的一维数组,删除其中重复元素,返回删除后数组长度,要求不另开内存空间. C++ 很简单的题目,但是第一发RE了,找了很久问题出在哪.最后单步调试发现vector.size()返回值是unsigned型的.unsigned型和int型数据运算结果还是unsigned型的.这就导致当数组为空时,nums.size(…

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…

国外的表达思维跟咱们有很大差别,做这道题的时候很明显.简单说本题就是让你把有序数组中的重复项给换成正常有序的.比如 1 2 2 3换成 1 2 3 3,根本不需要考虑重复的怎么办,怎么删除重复项等等.拿起键盘干就行了.然后返回有序项的下标就可以. Given a sorted array, remove the duplicates in place such that each element appear only once and return the new length. Do not…
