有一个90分钟的球赛，有n个分钟是有趣的，如果连着15分钟都是无趣的话，这个人就会离开

问你这个人看了多久的电视

题解：

数据范围才90，我还能说什么呢？

直接暴力吧

代码

#include<bits/stdc++.h>

using namespace std;

const int maxn = 1e5+7;

int v[100];

int main()

{

    int n;scanf("%d",&n);

    for(int i=1;i<=n;i++)

    {

        int x;scanf("%d",&x);

        v[x]=1;

    }

    int now=0,sum=0;

    for(int i=1;i<=90;i++)

    {

        sum++;

        if(v[i])now=0;

        else now++;

        if(now==15)

        {

            break;

        }

    }

    printf("%d\n",sum);

}
