使用編輯距離我必須找到兩個字符串之間有多少編輯,我已經在下面的代碼中完成了這些編輯,但是im卡住的部分正在打印輸出假設要查看的2d數組像這樣: 關於編輯距離的困惑
int editdistance(char *s, int ls, char *t, int lt)
{
int a, b, c;
if (!ls) return lt;
if (!lt) return ls;
if (s[ls] == t[ls])
return editdistance(s, ls - 1, t, lt - 1);
a = editdistance(s, ls - 1, t, lt - 1);
b = editdistance(s, ls, t, lt - 1);
c = editdistance(s, ls - 1, t, lt );
if (a > b) a = b;
if (a > c) a = c;
return a + 1;
}
int main()
{
char s1[100];
char s2[100];
printf("first: \n");
scanf("%s",s1);
printf("second: \n");
scanf("%s",s2);
printf("edit distance: %d\n", editdistance(s1, strlen(s1), s2, strlen(s2)));
return 0;
}
