 1 Link of codechef submission : https://www.codechef.com/viewsolution/20852630 Link if you directly want to fork in online compiler : https://ideone.com/NN1rqk Please explain where are the things going wrong. asked 19 Oct '18, 17:29 1★geek0 11●2 accept rate: 0%

 0 I think the problem is with how you're counting groups of 2, specifically the way you're calculating 2^n. It's not very clear. If you explained what you calculated a little better, it would help. We want to calculate $\frac{(2n)!}{2^n n!}$ Here is my code. It might be helpful to you. answered 19 Oct '18, 21:30 58●5 accept rate: 5% I think the problem is with something else, see this groups of tow works fine... https://ideone.com/apGeHx (20 Oct '18, 13:20) geek01★
