Can you solve this real interview question? Number of Longest Increasing Subsequence - Given an integer array nums, return the number of longest increasing subsequences. Notice that the sequence has to be strictly increasing. Example 1: Input: num
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...
