My submission: https://codeforces.com/contest/1613/submission/161506133 Please someone help. I think I wrote the code correctly. It shouldn't get -1 as output(it may print any other wrong value but not -1)

Your variable
ans
is zero modulo $$$998244353$$$ and you subtract $$$1$$$ from it. So your result is $$$-1$$$ but it should be $$$998244352$$$ (this is the same $$$-1$$$ but modulo $$$998244353$$$). So you should print something like(ans - 1 + M) % M
instead ofans - 1
.Ah...Got it . Thanks a lot man!
