using namespace std;

int main()
{
    int l,zero=0,one=0;
    string ch1;
    cin>>ch1;
    ch=ch1;
    l=ch1.length();
    for(int i=1;i<l;i++)
    {
        cin>>ch1;
        ch=ch+ch1;
    }
    cout<<l<<" ";
    for(int i=0;i<l*l;i++)
    {
        if(ch[i]=='0')
        {
            if(one>0)
            {
                cout<<one<<" ";
                one=0;
            }
            zero++;
        }
        else
        {
            if(zero>0)
            {
                cout<<zero<<" ";
                zero=0;
            }
            one++;
        }
    }
    if(zero!=0)  //输出最后一个数字
        cout<<zero;
    else
        cout<<one;
    return 0;
