they used read() then .split and . split apparently....
or something like that in python
I used fin>> and grabbed a char at a time, since fin ignores whitespaces, I was safe

I ended up getting 1/5 after BS'ing something together when I lost my train of thought for what to do with 45 mins left. Had an idea for a solution but I believe it would have timed out anyway with a large test case. But I have a question about #2. I got 4/5 during the contest, but when I ran it against the given test data it came out exactly like the posted correct answers. Could you look into this? The team name is "Better than Drew and Paul" I would at least like to know which test case it said that I had got wrong originally. When I checked the output it said it ran fine and it ran perfect here. Also, no code changes between submissions and testing. EDIT: So after looking at the actual solution, I guess I had the right idea for the solution but I wasn't going to construct it properly at all. |

I've split out your post from another thread, so that the questions don't get mixed up. Your solution was correct, but you've ended up printing capital Xs instead of lowercase x. |

Ok thanks. I figured that was the issue once I looked back at the problem after I instantly resubmitted the exact same solution. Figured that might have been it. Oh well. Thanks for the response Tony. Great contest |

i think alot of people in my school got low scores for this question because of the space after the 2 numbers during the input. At least that's what they said, that extra space wasn't mentioned in the contest and it screwed some non token based inputs. I was also wondering does the second submission for any question have the same input set? |

Second submission has the same cases, but in different order. |

How would an extra space mess things up? Were hey using a getline type function and breaking the string down into integers? I realize some languages require this (python) but even still, after a bit of experience with it, you would think that you would be careful in case there is a space there |

I used c++ and just used in >> int1 >> int2; It reads in the numbers perfectly fine and I was golden. I know some of my friends used python last year (think they moved to c++ now mostly) but have no idea how they would have split it to get the input. Just know that it cost us a few hours over the course of a few contests when we worked together trying to get input to read properly |
