将下列代码转化为python代码map<string,string> word;//记录单词 map<string,int>m;//记录词频 map<string ,string>::iterator it; int level = 0; vector<string> ans; struct TrieNode{ bool isOver = false;//判断是不是单词结尾 char data = NULL; struct TrieNode *child[26];//下层节点 }; TrieNode *CreatTrie(void){ //建树 TrieNode *root = new TrieNode; for(int i = 0 ; i < 26 ; i++) { root->data = NULL; root->child[i] = NULL; } root->isOver = false; return root; };

it = word.items()

class TrieNode:
def __init__(self):

for i in range(26):

用py写一段代码 <div class="page"><b>1</b><a href="/dongman/index_2.htm">2</a><a href="/dongman/index_3.htm">3</a><a href="/dongman/index_4.htm">4</a><a href="/dongman/index_5.htm">5</a><a href="/dongman/index_6.htm">6</a><a href="/dongman/index_7.htm">7</a><a href="/dongman/index_8.htm">8</a><span class="slh">…</span><a href="/dongman/index_116.htm">116</a><a href="/dongman/index_2.htm" class="prev">下一页></a></div> 这是我的思路 取所有htm|\"(.*?)</然后输出最大的数
你使用正则表达式来提取字符串中的数字找到其中的最大值。以下是Python实现的代码示例:
```
import re
html_string = '<div class="page"><b>1</><a href="/dongman/index_2.htm">2</a><a href="/dongman/index_3.htm">3</aa href="/dongman/index_4.htm">4</a><a href="/dongman/index_5.htm">5</a><a href="/dongman/index_6.htm">6</a><a href="/dongman/index_7.htm">7</a><a href="/dongman/index_8.htm">8</a><span class="slh">…</span><a href="/dongman/index_116.htm">116</a><a href="/dongman/index_2.htm" class="prev">下一页></a></div>'
numbers = re.findall(r'\d+', html_string)
max_number = max(map(int, numbers))
print(max_number)
```
这段代码会输出数字中的最大值,即116。它首先使用正则表达式`r'\d+'`匹配字符串中的所有数字,然后将这些数字转换为整数并找到其中的最大值,最后打印出来。
#include<iostream> #include<string> using namespace std; int x=1; struct node { int num; node *next;//定义结构体 }*head; int main() { int n,m; cin>>n>>m; head=new node(); node *s,*r,*p,*pre; int i; r=head; for(i=0;i<n;i++)//尾插法 { s=new node(); s->num=x; x++; r->next=s; r=s; } r->next =head->next;//使最后一个节点指向第一个节点 p=head; for(int j=0;j<n;j++) { for(int k=0;k<m-1;k++) { p=p->next ; }//p为要去小孩的前一个 cout<<p->next->num<<" "; p->next=p->next->next;去掉p后面的那个小孩 } // system("pause"); return 0; }转变为Python代码
```python
n, m = map(int, input().split())
x = 1
head = {'num': None, 'next': None}
r = head
for i in range(n):
s = {'num': x, 'next': None}
x += 1
r['next'] = s
r = s
r['next'] = head['next'] # 使最后一个节点指向第一个节点
p = head
for j in range(n):
for k in range(m - 1):
p = p['next'] # p为要去小孩的前一个
print(p['next']['num'], end=' ')
p['next'] = p['next']['next'] # 去掉p后面的那个小孩
```
