题目如下: Given an array A of integers, return the length of the longest arithmetic subsequence in A. Recall that a subsequence of A is a list A[i_1], A[i_2], ..., A[i_k] with 0 <= i_1 < i_2 < ... < i_k <= A.length - 1, and that a sequence B is…

Given an unsorted array of integers, find the length of longest increasing subsequence. For example, Given [10, 9, 2, 5, 3, 7, 101, 18], The longest increasing subsequence is [2, 3, 7, 101], therefore the length is 4. Note that there may be more than…

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…

题目如下: Given two strings text1 and text2, return the length of their longest common subsequence. 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…
