If $\lambda=(\lambda_1\geq\lambda_2\geq\dots\geq\lambda_k)\vdash n$ is an integer partition of $n$ then $\lambda_1$ is its largest part and $k$ is its length, $\ell(\lambda)$.

Define the statistic $c_n(\lambda)=\max\{\lambda_1,\ell(\lambda)\}$ for the above partition. Also consider the polynomial (in $t$),
$$Q_n(t)=\sum_{\lambda\vdash n}t^{c_n(\lambda)}.$$
Here are some examples: 

                               t

                                 2
                              2 t 

                              3    2
                           2 t  + t 

                           4      3    2
                        2 t  + 2 t  + t 

                          5      4      3
                       2 t  + 2 t  + 3 t 

                      6      5      4      3
                   2 t  + 2 t  + 4 t  + 3 t 

                   7      6      5      4      3
                2 t  + 2 t  + 4 t  + 5 t  + 2 t 

                8      7      6      5      4    3
             2 t  + 2 t  + 4 t  + 6 t  + 7 t  + t 

             9      8      7      6      5      4    3
          2 t  + 2 t  + 4 t  + 6 t  + 9 t  + 6 t  + t 

          10      9      8      7       6       5      4
       2 t   + 2 t  + 4 t  + 6 t  + 10 t  + 11 t  + 7 t 

**QUESTION 1.** It appears that the coefficients of $Q_n(t)$, read from left to right, are twice the partition numbers $1,1,2,3,5,7,11,15,\dots$, up to (at least) the middle term. Is this true?

**QUESTION 2.** Is there a generating function for the polynomials $Q_n(t)$?
