Vasya and Golden Ticket：

 暴力解决用所有可能的值试一遍：

#include "iostream"

#include "algorithm"

using namespace std;

int main()

{

 int n;

 cin>>n;

 char array[n+1];

 getchar();

    gets(array);

    int b[n];

    int num=0,t=0;

    for (int i = 0; i < n; ++i) {

        b[i]=array[i]-48;

        num+=b[i];

        if(b[i]>t)t=b[i];

    }

    int num1=0;

    for (int i = t; i <=num/2; ++i) {

        int x=0,y=0;

        for (int j = 0; j < n; ++j) {

            x+=b[j];

            if(i==x){

                x=0;

                y++;

            }

            else if(x>i)break;

        }

        if(x==0&&y>1){

            num1=1;

            break;

        }

    }

    if(num1==1)cout<<"YES";

    else cout<<"NO";

    return 0;

}
