Simulate the game using the minmax algorithm and you should see a pattern..Repon kumar Roy wrote: ↑Fri Nov 28, 2014 3:50 pmMy question is State (2,2) , can player give valid move , because no box with fewer items..

Hello there,
What algorithms did you use to solve this problem?
My idea was to build a DAG out of strongly connected components and then traverse the graph from the entry till the exit node while keeping track of the vertices being visited. But WA..
Any guidance on this problem?
Thanks!

I am using "normal" dfs for this problem. I number each node and when I hit an already visited node, I get the number of nodes in the cycle by the difference of their ids + 1. But WA :( Any catch?

Re: 11933 - Splitting Numbers
C++ function __builtin_ffs(x) was very handy for this problem. Used it to get the position of the least significant bit of an integer.

Re: 12507 - Kingdoms
Using a bruteforce approach to solve this problem was enough. 2^n sets of towns to be connected using MST and keeping the best configuration, which is the cost <= K and the configuration having the most number of connected people. This took around 0.103s. As I can see runtimes of 0.03s as well, what...

When you output the number of cards in the winner's hand, it should right justified in a field of width 3 (specified in the problem statement).
