题目描述 给定两个字符串,你需要从这两个字符串中找出最长的特殊序列.最长特殊序列定义如下:该序列为某字符串独有的最长子序列(即不能是其他字符串的子序列). 子序列可以通过删去字符串中的某些字符实现,但不能改变剩余字符的相对顺序.空序列为所有字符串的子序列,任何字符串为其自身的子序列. 输入为两个字符串,输出最长特殊序列的长度.如果不存在,则返回 -1. 示例 : 输入: "aba", "cdc" 输出: 3 解析: 最长特殊序列可为 "aba"…

problem 521. Longest Uncommon Subsequence I 最长非共同子序列之一 题意: 两个字符串的情况很少,如果两个字符串相等,那么一定没有非共同子序列,反之,如果两个字符串不等,那么较长的那个字符串就是最长非共同子序列. solution: class Solution { public: int findLUSlength(string a, string b) { ; return max(a.size(), b.size()); } }; or class…

Question 521. Longest Uncommon Subsequence I Solution 题目大意:给两个字符串,找出非共同子串的最大长度 思路:字符串相等就返回-1,不等就返回长度大的那个长度 Java实现: public int findLUSlength(String a, String b) { int aLength = a.length(); int bLength = b.length(); if (aLength != bLength) return Math.…

这是悦乐书的第252次更新,第265篇原创 01 看题和准备 今天介绍的是LeetCode算法题中Easy级别的第119题(顺位题号是521).给定一组两个字符串,您需要找到这组两个字符串中最长的不同子序列.最长的不同子序列被定义为这些字符串之一的最长子序列,并且此子序列不应该是其他字符串的任何子序列. 子序列是可以通过删除一些字符而不改变其余元素的顺序从一个序列导出的序列.任何字符串都是其自身的子序列,空字符串是任何字符串的子序列.输入将是两个字符串,输出需要是最长的不同子序列的长度.如果最长…

题目如下: 解题思路:因为given list长度最多是50,我的解法就比较随意了,直接用一个嵌套的循环,判断数组中每个元素是否是其他的subsequence,最后找出不属于任何元素subsequence的最长元素即可. 代码如下: class Solution(object): def isSubsequence(self, a, b): """ :type a: str :type b: str :rtype: int """ s = b f…
