you solved this with very naive approach. this wont work even for n=10.
think about it. when n=10, 2n=20, and (2n)! will cross all the limits of numeric data type.

to implement it, read some ideas through https://www.geeksforgeeks.org/program-nth-catalan-number/ link. and try to code it again.

thanks
