这篇文章通过LeetCode 300. Longest Increasing Subsequence 最长递增子序列来讲解 Dynamic Programming.本文列举3种不同的java解法,其中两种解法基于同一个解题思路,只是实现有所区别。 Question:Given an unso…
Example 2: Input: [2,2,2,2,2] Output: 5 Explanation: The length of longest continuous increasing subsequence is 1, and there are 5 subsequences' length is 1, so output 5. Note: Length of the given array will be not exceed 2000 and the answer is guaranteed to be fit in 32-bit si...

Longest consecutive sequence path is2-3, not3-2-1, so return2. 分析 这种题思路比较直接,就是维护一个最大值,DFS遍历整个树,不断更新最大值。函数里可以包含父节点的值及当前连续长度,如果发现本身值跟父节点值不连续,当前连续长度变为1,否则增加当前连续长度。

47 thoughts on “LeetCode – Longest Consecutive Sequence (Java)” alexwest11 June 19, 2022 at 6:34 am could we just put all into hash, and for each element check if NOT exist (-1) so, it is start of new consec seq and check all next elements: +1 +2 …?
