back to boardI can also say, that it is the first test in which N has more than 1000 digits ... I think 10000 = MMMMMMMMMM So I output 10... Is this right? No, you are wrong. The answer is 1, because all the numbers 10^k and 5*10^k are written in Pseudo-Romanian system with only 1 (maybe very unusual) digit. |
