        cin >> k[i];
    cp.resize(N);
    cp=k;
    vector<int>ans;
    sort(cp.begin(),cp.end());
    ans.resize(cp[N-1]+1);
    for(l=1,j=0;l<(cp[N-1]+1);l+=(++j))

1) Any reason to use std::sort() instead of std::maximum_element() to find maximum element?

2) > ans.resize(cp[N-1]+1);
What maximum value of "cp[N-1]+1" is? Isn't it 2^31-1?
