Recently I have tried to do few Olympiad problems to get my logic up to speed however whilst doing a question, I was left confused with the question. To elaborate, please look at question 2: Die Tipping on 2010 British Olympiad Paper: http://www.olympiad.org.uk/papers/2010/bio/bio-10-exam.pdf
Now, I understand the concept of what it asks me to do however in page 4 of the paper it shows a sample input and output so firstly I understand the first input:
1 3 5
1 6 5
1 1 5
I understand that it is taking in the 3x3 board however the output after the next move confused me very much:
1 1 1
1 3 5
1 1 5
I don't see how that could be possible as firstly the die will start at coordinate (1,0) (i.e the part of the grid-inputted which was 3) and since the die is in its default orientation (1 facing up and 6 facing down) when next move happens surely the board should be:
1 4 1
1 2 5
1 1 5
Could someone explain what is wrong in my logic or at least write a re-mastered version of the question which is more clear?
