Hope follow case helps. Accetped output: As mentioned aboved, no character with a code equal to 0.

Here is some input - output for those getting WA. Also note that you don't need to use edmonds-karp/ford-fulkerson algorithm to solve this problem. It's a bipartite graph and can be solved by an n^3 algorithm explained here. http://www.geeksforgeeks.org/maximum-bipartite-matching/ Output for this i...

The test data of this problem seems not very strong, otherwise BigInteger should be used to get accepted.

I used signed int for score and got accepted.

I agreed with extremegf.

You need to notice the type T movement, if Knight stands (1, 1) at start in a board with size 20*20, It can move to (20, 1) or (1, 20), but not (2,1), (1,2), (4,1), (1, 4), ... remember that the movement is mirror reflection with respect to board and one of axes parrelle to board sides. Secondly, th...

Comfirmed by using assert in C++:
(1) There is no dupciliated point in star map or constellation in judge data.
(2) There is no need to handle symmetrical constellations, because all constellation are not symmetrical in judge data.

The solution on uDebug seems buggy. Output of uDebug is "solution", but it's impossible to get "10" just using "+1xx0358+80".
