The subsequence [2,1] has a sum less than or equal to 3. It can be proven that 2 is the maximum size of such a subsequence, so answer[0] = 2. The subsequence [4,5,1] has a sum less than or equal to 10. It can be proven that 3 is the maximum size of such a subsequence...
Can you solve this real interview question? Longest Harmonious Subsequence - We define a harmonious array as an array where the difference between its maximum value and its minimum value is exactly 1. Given an integer array nums, return the length of it
给出一个无序的整形数组,找到最长上升子序列的长度。 例如, 给出[10, 9, 2, 5, 3, 7, 101, 18], 最长的上升子序列是[2, 3, 7, 101],因此它的长度是4。因为可能会有超过一种的最长上升子序列的组合,因此你只需要输出对应的长度即可。 解题思路 用动态规划思想,考虑用一个数组dp记录到当前数字为止...

Longest Common Subsequence 给出两个字符串,找到最长公共子序列(LCS),返回LCS的长度。 说明 最长公共子序列的定义: • 最长公共子序列问题是在一组序列(通常2个)中找到最长公共子序列(注意:不同于子串,LCS不需要是连续的子串)。该问题是典型的计算机科学问题,是文件差异比较程序的基础,在生物信息学中也有所应用...
class Solution: def longestCommonSubsequence(self, text1: str, text2: str) -> int: m, n = len(text1), len(text2) # dp[i][j] 表示 text1[..i] 和 text2[..j] 的最长公共子序列的长度 dp = [[0] * (n + 1) for _ in range(m + 1)] for i in range(m): for j in ra...

Input: arr = [1,5,7,8,5,3,4,2,1], difference = -2 Output: 4 Explanation: The longest arithmetic subsequence is [7,5,3,1]. 来源:力扣(LeetCode) 链接:https://leetcode-cn.com/problems/longest-arithmetic-subsequence-of-given-difference 著作权归领扣网络所有。商业转载请联系官方授权,非商...
Output: 4 Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4. Note: There may be more than one LIS combination, it is only necessary for you to return the length. Your algorithm should run in O(n2) complexity. ...
