求括号内单词数和括号外最大单词长度，注意细心，尤其是ok和sum的置0。

 

 

#include<iostream>
#include<cstring>
#include<cstdio>
#include<algorithm>
#include<cmath>
#define INF 0x3f3f3f3f
using namespace std;

int main()
{
    int n;
    char s[300];
    scanf("%d",&n);
    getchar();
    gets(s);
    int maxx = 0,cnt = 0,flag = 0,ok = 0,sum = 0;
    for(int i = 0;i < n;i++)
    {
        if(s[i] == ‘(‘)
        {
            flag = 1;
            ok = 0;
        }
        else if(s[i] == ‘)‘)
        {
            sum = 0;
            flag = 0;
            if(ok)    cnt++;
        }
        else if(flag == 0)
        {
            if(s[i] == ‘_‘)    sum = 0;
            else
            {
                sum++;
                maxx = max(sum,maxx);
            }
        }
        else if(flag == 1)
        {
            if(s[i] == ‘_‘)
            {

                ok = 0;
            }
            else    ok = 1;
        }
    }
    printf("%d %d\n",maxx,cnt);
