In OddLand, there are many odd shops.
These shops only sell goods weighted from 1 to 10. For every weight i in [1,10], there are $a_i$ kinds of goods weighted i.
The shops are odd because one is only allowed to buy one item or nothing in each shop. And though goods in every shop are different, the array $a$ for each shop is the same.
As you love odd things so much, you wonder for how many total weights, there are odd ways to buy items in n odd shops to achieve this total weight. Since there might be many, output the number mod 998244353.
