---------------------------------------------------------------------- 解法一:空间换时间 我使用的办法也是类似于"扫描-拷贝"这种的,不过稍微有些不同,是使用了一个队列来记录空闲的位置信息,然后每次需要移动的时候出队列就可以了,这样可以做到最少的拷贝次数. 扫描到一个元素的时候情况可能有以下几种:nums[i]==0   --> 放入下标队列,没有元素移动nums[i]!=0 && !queu…

这是悦乐书的第201次更新,第211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67题(顺位题号是283).给定一个数组nums,写一个函数将所有0移动到它的末尾,同时保持非零元素的相对顺序.例如: 输入:[0,1,0,3,12] 输出:[1,3,12,0,0] 注意: 您必须在不制作数组副本的情况下就地执行此操作. 最小化操作总数. 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 64位系统,使用Java语言编写和测试. 02…
