输入有问题
这种输入在本地exe中要用^Z（Ctrl + Z）结束

#include<iostream>
using namespace std;
#include<vector>
int main()
{
    int n = 1;
    int N;
    cin >> N;
    vector<int>a;
    int temp;
    while (cin >> temp) a.push_back(temp);//here

//    int k = 0;

    int b = 0;
    for(int r=0;r<a.size();r++)
    {
        for (int j = 0; j < a[r]; j++)
        {
            cout << r % 2;
            b++;
            if (b == N&&n!=N)
            {
                cout << endl;
                b = 0;
                n++;
            }
        }
        /*
        if (k == 0)
        {
            k = 1;
        }
        else
        {
            k = 0;
        }
        */

    }
    return 0;
}
