给你一个整数数组 nums ,找到其中最长严格递增子序列的长度。
nums
子序列是由数组派生而来的序列,删除(或不删除)数组中的元素而不改变其余元素的顺序。例如,[3,6,2,7] 是数组 [0,3,1,6,2,2,7] 的子序列。
[3,6,2,7]
[0,3,1,6,2,2,7]
示例 1:
输入:nums = [10,9,2,5,3,7,101,18] 输出:4 解释:最长递增子序列是 [2,3,7,101],因此长度为 4 。
示例 2:
输入:nums = [0,1,0,3,2,3] 输出:4
示例 3:
输入:nums = [7,7,7,7,7,7,7] 输出:1
提示:
进阶:
你可以设计时间复杂度为 O(n2) 的解决方案吗? 你能将算法的时间复杂度降低到 O(n log(n)) 吗?
O(n log(n))
