数组的尺寸为(len(s1)+1) x (len(s2)+1),因为我们还需要考虑到源字符串和目标字符串为空的情况。 defedit_distance(s1,s2):# 获取两个字符串的长度len_s1=len(s1)len_s2=len(s2)# 创建一个二维数组,初始化为0dp=[[0]*(len_s2+1)for_inrange(len_s1+1)]returndp 1. 2. 3. 4. 5. 6....
Edit distance, also known as Levenshtein distance, is a measure of the similarity between two strings. It calculates the minimum number of operations required to transform one string into another, where each operation can be an insertion, deletion, or substitution of a single character. In this ...
python实现编辑距离edit distance 1.定义理解 edit distance——指两个字符串之间,一个转为另一个的最小编辑次数(方式有:插入/删除/替换) 若edit distance越小,则字符串之间的相似度越高。 例1: 输入: word1 = "horse", word2 = "ros" 输出: 3 解释: horse -> rorse (将 'h' 替换为 'r') rors...
接下来,我们通过Python代码实现编辑距离的动态规划方法。 defedit_distance(word1:str,word2:str)->int:m,n=len(word1),len(word2)# 创建一个二维数组,用于存储子问题的解dp=[[0]*(n+1)for_inrange(m+1)]# 初始化边界条件foriinrange(m+1):dp[i][0]=i# 需要删除 i 个字符forjinrange(n+1)...
Graph Traversal Edit Distance (GTED) is a measure of distance (or dissimilarity) between two graphs introduced. This measure is based on the minimum edit distance between two strings formed by the edge labels of respective Eulerian traversals of the two graphs. GTED was motivated by and ...
