here is my code:
#include<iostream>
using namespace std;
#include<string>
#include<cctype>
int main()
{
    string str[201],universityname[201];
    int n,m,i,j,k=1;
    cin>>n>>n>>m;
    getchar();
    i=0;
    while(i<n)
    {
        getline(cin,str[i]);
        i++;
    }
    for(i=0;i<n;i++)
    {
        for(j=0;j<str[i].length();j++)
            if(str[i][j]==' '&&str[i][j+1]=='#')
                break;
        for(k=j-1;k>=0;k--)
            if(str[i][k]==' ')
                break;
        universityname[i].assign(str[i],0,k);
    }
    for(i=0;i<n;i++)
        for(j=0;j<universityname[i].length();j++)
            universityname[i][j]=tolower(universityname[i][j]);
    k=1;
    for(i=0;i<n;i++)
    {
        for(j=0;j<i;j++)
            if(universityname[i]==universityname[j])
                break;
            else
                if(j==i-1)
                    k++;
        if(k>=m) break;
    }
    cout<<str[i]<<endl;
    return 0;
}
