LCS(最长公共子序列)和dp(动态规划)
参照:v_JULY_v        最长公共子序列定义:         注意最长公共子串(Longest CommonSubstring)和最长公共子序列(LongestCommon Subsequence, LCS)的区别:子串(Substring)是串的一个连续的部分,子序列(Subsequence)则是从不改变序列的顺序,而从序列中去掉任意的元素而获得的新序列;更简略地说,前者(子串...

最大子序列和(Max Subsequence Sum)问题求解
给定(可能有负的)整数A1,A2,…,AN,求 的最大值。 例如:输入4,-3,5,-2,-1,2,6,-2,最大子序列和为11(从A1到A7)。 算法1:最直观的算法,穷举式地尝试所有可能。下标变量i表示子序列的开始位置,j表示结束位置,每次选定一个子序列Ai--Aj,再使用k遍历该子序列求子序列...
