You're right eloha, BFS can solved this problem. There are something wrong with my BFS. Now I got AC.

Thanks, for reply Dominik. I think this problem can't be solve by construct a complete difference table, so I try to find some equation that satisfy this condition. If the extrapolation difference is n, the eqution become : y(x) = Ax + B.x^2 + C.x^3 + D.x^4 + ... +K1.x^n + K2 where K1 and K2 some co...

571-Jugs-BFS ?

I use BFS to break this problem, but get TLE.
Is this problem can't be done using BFS ?
Am I in the right track ?

Thanks.

Hi eloha, I have the same problem with you, get WA. can you check my code whats wrong with them? #include <stdio.h> #include <string.h> #include <stdlib.h> #define delenter(s) if(s[strlen(s)-1] == '\n') s[strlen(s)-1] = '\x0' typedef struct { int left, right; }t_tree; t_tree tree[10008]; int inord[1...

I think precalculated cannot be applied here, since the number is very huge. :lol:

Sure, This is modulo 9 congruence problem. If x,y is a vampire number then : x.y == x+y (mod 9) The solution of the above formula is (x mod 9, y mod 9) : (0,0), (2,2), (3,6), (5,8), (6,3) , and (8,5). so you find for (x mod 9, y mod 9) that satisfy the above condition and check whether the number is...

I've got AC when using BFS algorithms. I really don't know why DFS can't solve this problem...

m should be :
unsigned long long int m;
Hi,
I got AC when using long long, so I think that's not the problem.

Use modulo congruence(I find it in the net).
