[LeetCode 128] - 最長連續序列(Longest Consecutive Sequence)
問題 給出一個未排序的整數數組，找出最長的連續元素序列的長度。 如： 給出[100, 4, 200, 1, 3, 2]， 最長的連續元素序列是[1, 2, 3, 4]。返回它的長度：4。 你的算法必須有O(n)的時間復雜度。 初始思路 要找連續的元素，第一反應一般是先把數組排序 ...

[LeetCode]Longest Consecutive Sequence
題目大意 給定一個整形數組，求出最長的連續序列。例如數組[100,4,200,1,3,2]，最長的連續序列長度為[1,2,3,4]，長度為4。要求時間復雜度為O(n)。 思路 "排序轉換成經典的動態規划問題"的話排序至少需要時間復雜度為O(nlog(n))——pass ...
