与 最长公共子序列类似 只是最长公共子串必须连续 所以只能走斜线!!!! ''' LCS 最长公共子序列 ''' def LCS_len(x, y): m = len(x) n = len(y) dp = [[0] * (n + 1) for i in range(m + 1)] B = [[' '] * (n + 1) for i in range(m + 1)] for i in range(1, m + 1): for j in range(1, n + 1): if x[i - 1] =…
#!一个序列S任意删除若干个字符得到的新序列T,则T叫做S的子序列 注意,这个和最长公共字串不一样,最长公共子串要求连续. 1.算法公式: def lcs(a,b): lena = len(a) lenb = len(b) c=[[0]*(lenb+1) for j in range(lena+1) ] flag = [[0]*(lenb+1) for j in range(lena+1) ] for i in range(lena+1)[1:]: for j in range (lenb+1)…
