Longest Consecutive Sequence Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example,Given [100, 4, 200, 1, 3, 2],The longest consecutive elements sequence is [1, 2, 3, 4]. Return its length: 4.…

题目 给定一个未排序的整数数组,找出最长连续序列的长度. 要求算法的时间复杂度为O(n). 示例: 输入:[100, 4, 200, 1, 3, 2] 输出:4 解释:最长连续序列是[1, 2, 3, 4].它的长度为4 思路 思路一 先由小到大进行排序 考虑三种情况: 前后相差1,则是连续序列 前后相等,循环continue 最后一个元素,break 代码 def longestConsecutive(nums) -> int:     if nums:         nums.sort()…

Given an unsorted array of integers, find the length of the longest consecutive elements sequence. For example,Given [100, 4, 200, 1, 3, 2],The longest consecutive elements sequence is [1, 2, 3, 4]. Return its length: 4. Your algorithm should run in…

Given an unsorted array of integers, find the length of longest continuous increasing subsequence. Example 1: Input: [1,3,5,4,7] Output: 3 Explanation: The longest continuous increasing subsequence is [1,3,5], its length is 3. Even though [1,3,5,7] i…

给定一个未经排序的整数数组,找到最长且连续的的递增序列. 示例 1: 输入: [1,3,5,4,7] 输出: 3 解释: 最长连续递增序列是 [1,3,5], 长度为3. 尽管 [1,3,5,7] 也是升序的子序列, 但它不是连续的,因为5和7在原数组里被4隔开. 最长连续递增子序列,解法就直接模拟,从1-n,要是a[i]<a[i+1],长度加一,碰到a[i]>=a[i+1]就更新最长的递增序列长度 class Solution { public: int findLengthOfLCIS(v…
