#2

@dips123deepali_c25f140838182212,
`
for (int i = 0; i < n; i++)
{
cin >> temp; // here input is taken

    if (freq.find(temp) != freq.end() && freq[temp] > 0)
    {
        freq[temp]--; //Decrement frequency to ensure it is not repeated
        ans.push_back(temp);
    }
}

`

and the line freq(temp)!=m.end(); means while freq of temp is not 0

is the doubt clear?
