Given an integer arraynums, returnthe number of longest increasing subsequences. Example 1: Input: nums = [1,3,5,4,7] Output: 2 Explanation: The two longest increasing subsequences are [1, 3, 4, 7] and [1, 3, 5, 7]. Example 2: Input: nums = [2,2,2,2,2] Output: 5 Explan...
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 signed int. 这道题给了我们一个数组,让求最长递增...

This is a weighted version of a result of Bollobás and Leader. As a corollary, one obtains a result of Adhikari, Chen, Friedlander, Konyagin and Pappalardi. A result of Yuan and Zeng on the existence of zero-smooth subsequences and the DeVos–Goddyn–Mohar Theorem are some of the main ...
