A 3BV de uma placa Minesweeper representa o número mínimo de cliques esquerdos necessários para resolver a placa, se você já conhece a solução. Significa "Valor de referência do conselho da Bechtel". Aqui está o site dele explicando isso.
Abaixo está uma placa do Campo Minado resolvida. As bandeiras indicam minas; ladrilhos sem minas indicam a contagem de minas adjacentes, inclusive na diagonal, exceto que os ladrilhos que deveriam ter "0" são deixados em branco. A imagem mostra em quais blocos é necessário clicar para resolver o quadro.
Os cliques contados no 3BV são:
- Um para cada área cheia de ladrilhos em branco (zero minas adjacentes) e seus vizinhos não em branco.
- Um para o outro lado a lado não-mina.
Outro exemplo (3BV = 39)
Dada uma matriz de valores 2D, 0
para clear e 1
para uma mina (ou um booleano), retorne o 3BV .
As dimensões de uma placa terão pelo menos 8x8 e, no máximo, 24x30, inclusive. Seu programa deve lidar com todas as placas possíveis, não apenas com os exemplos.
Nota: Um tabuleiro nunca conterá apenas minas.
