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 in place with constant memory. For example, Given input array…

题目 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 doe…

题目 Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2->3->3, return 1->2->3. 分析 该题目与LeetCode 83题目类似,都是删除链表中重复元素的题目. 该题目要求只保存不重复的结点! 详…

题目 Given a sorted linked list, delete all duplicates such that each element appear only once. For example, Given 1->1->2, return 1->2. Given 1->1->2->3->3, return 1->2->3. 分析 删除链表中反复元素结点. 该题目本质非常easy.仅仅需一次遍历.须要注意的是.要释放删除的结点空间. A…

LeetCode第26题 Given a sorted array nums, 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)…

problem: 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 ar…

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…

题目 Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e., 0 1 2 4 5 6 7 might become 4 5 6 7 0 1 2). You are given a target value to search. If found in the array return its index, otherwise return -1. You may assume no dup…
