还有一种稍微复杂点的方法,参见我的另一篇博客Longest Increasing Subsequence,那是 LintCode 上的题,但是有点不同的是,那道题让求的 LIS 不是严格的递增的,允许相同元素存在。 Github 同步地址: https://github.com/grandyang/leetcode/issues/300 类似题目: Increasing Triplet Subsequence Russian Doll Envelopes ...
LeetCode -- Longest Increasing Subsequence(LIS) Question: Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given[10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is[2, 3, 7, 101], therefore the length is4. Note that...
