Problem Description A subsequence of a given sequence is the given sequence with some elements (possible none) left out. Given a sequence X = <x1, x2, ..., xm> another sequence Z = <z1, z2, ..., zk> is a subsequence of X if there exists a stri…
A subsequence of a given sequence is the given sequence with some elements (possible none) left out. Given a sequence X = <x1, x2, ..., xm> another sequence Z = <z1, z2, ..., zk> is a subsequence of X if there exists a strictly increasing sequ…
解题思路:先注意到序列和串的区别,序列不需要连续,而串是需要连续的,先由样例abcfbc abfcab画一个表格分析,用dp[i][j]储存当比较到s1[i],s2[j]时最长公共子序列的长度 a b f c a b 0 0 0 0 0 0 0 a 0 1 1 1 1 1 1 b 0 1 2 2 2 2 2 c 0 1 2 …
