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]. 标签: Array Two Pointers 分析 加一个变量...
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] 之前的想法是再加一个计数的变量就行了 intremoveDeplicates1(intA[],intn) {...
http://oj.leetcode.com/problems/remove-duplicates-from-sorted-array-ii/ 这道题跟Remove Duplicates from Sorted Array比較类似,差别仅仅是这里元素能够反复出现至多两次,而不是一次。事实上也比較简单。仅仅须要维护一个counter。当counter是2时,就直接跳过就可以,否则说明元素出现次数没有超,继续放入结果数组,若...

该题设部分有两个主要的关键点,其一是数组自身有顺序;其二是数组的本身返回仍是以袁数组nums的内容返回,预期不是采用新数组方式。 具体的一些复杂要求,可以去查看相关题设说明。 方法一: 使用双指针的方法,两个指针比较来进行移动. 其中i代表慢的指针,需要更新nums数组的值 ...
