$\begin{array}{c}(26 & = & 5+6+7+8 \\ 27 & = & 8+9+10 \\ 28 & = & 1+2+3+4+5+6+7 \\ 29 & = & 14+15 \\ 30 & = & 4+5+6+7+8 \\ 31 & = & 15+16 \end{array}$

If you see the above numbers , they can be represented as a sum of some consecutive numbers.If 32 can be expressed as $\displaystyle\sum_{i=1}^n a_i$ , where $a_1,a_2,a_3, \dots a_n$ are some consecutive positive numbers , compute $\displaystyle\prod_{i=1}^n a_i$.

Note: If you think that 32 is not lucky enough to have such representation , input the answer as 999.
