Given an array of integers nums and an integer target. Return the number of non-empty subsequences of nums such that the sum of the minimum and maximum element on it is less or equal to target. Since the answer may be too large, return it modulo 109 + 7. Example 1: Input: nums = ...
Given a stringsand an array of stringswords, returnthe number ofwords[i]that is a subsequence ofs. A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters. For exam...
Let's suppose in the general problem, we have 2 strings S and T, and we need to count the amount of subsequences in S that are equal to T. Let's denote |S| = n, |T| = k (|a| stands for string a's length). We can maintain an array dp[k], where each cell ...

https://leetcode.cn/problems/number-of-matching-subsequences/ Given a string s and an array of strings words, return the number of words[i] that is a subsequence of s. A subsequence of a string is a new string generated from the original string with some characters (can be none) delete...
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. ...
