Rascal's Triangle Formula

Revision en2, by Qualified, 2020-11-28 04:29:16

Recently, I stumbled upon Rascal's Triangle. You can read more about it here. Basically it is very like Pascal's Triangle but a bit different. I know that there is a $$$O(n)$$$ solution for Pascal's Triangle. I would want to calculate the $$$nth$$$ row in $$$O(n)$$$ mod $$$998244353$$$. Help?
