Uma forma direta de resolver o problema e remover todas as arestas que pertencem
a algum menor caminho original e, depois, calcular novamente o menor caminho.
Primeiro rodamos Dijkstra a partir de $S$ no grafo original, obtendo
$distS[u]$, a menor distancia de $S$ ate cada vertice $u$. Em seguida rodamos
Dijkstra no grafo reverso a partir de $D$, obtendo $distD[u]$, a menor
distancia de $u$ ate $D$ no grafo original.
Se $distS[D]$ for infinito, nao existe caminho de $S$ ate $D$ e a resposta ja e
$-1$.
Caso contrario, uma aresta direcionada $(u, v)$ de peso $p$ pertence a algum
menor caminho de $S$ ate $D$ se, e somente se:
\[
distS[u] + p + distD[v] = distS[D].
\]
Essa igualdade diz que existe um menor caminho formado por um menor caminho de
$S$ ate $u$, seguido pela aresta $(u, v)$, seguido por um menor caminho de $v$
ate $D$. Portanto, marcamos todas as arestas que satisfazem essa condicao como
removidas.
Por fim, rodamos Dijkstra mais uma vez a partir de $S$, ignorando as arestas
removidas. A distancia obtida ate $D$ e o quase menor caminho; se ela for
infinita, imprimimos $-1$.
Cada execucao de Dijkstra custa $O((N+M)\log N)$. Como usamos tres execucoes, a
complexidade total por caso de teste e $O((N+M)\log N)$ em tempo e $O(N+M)$ em
memoria.

\begin{ProblemaAutor}{}{Quase Menor Caminho}{1}{1536}{SPOJ Brasil}
Encontrar o menor caminho entre dois pontos em um mapa é um problema clássico.
Mas, em alguns sistemas de navegação, todas as rotas que fazem parte de algum
menor caminho podem ficar congestionadas. Nesse caso, queremos encontrar uma rota
alternativa.
O mapa é representado por um grafo direcionado e ponderado. Os vértices são
pontos do mapa, e cada aresta direcionada representa uma rota de um ponto para
outro com um certo comprimento.
O quase menor caminho entre a origem $S$ e o destino $D$ é o menor caminho de
$S$ até $D$ que não usa nenhuma aresta pertencente a qualquer menor caminho de
$S$ até $D$ no grafo original.
Sua tarefa é determinar o comprimento do quase menor caminho. Caso não exista
nenhum caminho que satisfaça essa condição, a resposta deve ser $-1$.
Por exemplo, suponha que a figura abaixo representa o mapa dado, com círculos
representando localizações e linhas representando rotas diretas, de mão única
com as distâncias indicadas. O ponto de partida está marcado como $S$ e o de
destino está marcado como $D$. As linhas em negrito pertencem a um caminho
mínimo (nesse caso existem dois caminhos mínimos, cada um com extensão \(4\)).
Logo, o quase menor caminho seria o indicado com linhas pontilhadas (extensão
\(5\)), já que nenhuma rota entre dois pontos consecutivos pertence a nenhum
caminho mínimo. Note que poderia existir mais de uma resposta possível, por
exemplo, se a rota com extensão \(3\) tivesse extensão \(1\). Bem como poderia
inexistir uma resposta certa.

\end{figure}
\Entrada
A entrada contem varios casos de teste.
A primeira linha de cada caso contem dois inteiros $N$ e $M$
($2 \leq N \leq 500$, $1 \leq M \leq 10^4$), representando o numero de
vertices e o numero de arestas direcionadas do grafo. Os vertices sao numerados
de $0$ a $N-1$.
A segunda linha contem dois inteiros $S$ e $D$
($0 \leq S, D < N$, $S \neq D$), representando a origem e o destino.
Cada uma das proximas $M$ linhas contem tres inteiros $U$, $V$ e $P$
($U \neq V$, $0 \leq U, V < N$, $1 \leq P \leq 1000$), indicando uma aresta
direcionada de $U$ para $V$ com peso $P$.
Existe no maximo uma aresta direcionada de um vertice $U$ para um vertice $V$.
A existencia de uma aresta de $U$ para $V$ nao implica a existencia de uma aresta
de $V$ para $U$.
O fim da entrada e indicado por uma linha contendo \texttt{0 0}.
\Saida
Para cada caso de teste, imprima uma linha contendo um unico inteiro.
Se existir um quase menor caminho, imprima seu comprimento. Caso contrario,
imprima $-1$.

\texttt{7~9} & \texttt{5}\\
\texttt{0~6} & \texttt{-1}\\
\texttt{0~1~1} & \texttt{6}\\

\texttt{0~0} & \\
\end{Exemplo}
\Notas
No primeiro caso da amostra, existem menores caminhos de custo $4$. Todas as
arestas que aparecem em algum desses caminhos sao descartadas. Depois disso, o
menor caminho restante tem custo $5$.
No segundo caso, todo caminho da origem ate o destino usa alguma aresta que
pertence a um menor caminho original, entao a resposta e $-1$.
