Hi, I was trying to follow the solution to the 2008 problem Ugly Numbers in Round 1C. I understand that it ought to be a Dynamic Programming solution. Also, x % 210 and y % 210 tell you (x+y)%210 and (x-y) % 210. However, I hope someone can help me with the following:
1. If the operation before character 'j' was '+', shouldn't the update be dyn[j-1][(x-d)%210] rather than the other way round? 2. Why is there a +MOD in the line dyn[j+1][(x+sgn*cur+MOD)%MOD] += dyn[i][x]; Note: I am following the solution from the Contect analysis at http://code.google.com/codejam/contest/dashboard?c=32015#s=a&a=1 Thanks! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "google-codejam" group.
