Você recebe uma matriz bidimensional de bytes do tamanho mx n. É garantido que todos os bytes sejam 1 ou 0. Encontre o número de retângulos representados por 1s quando visualizados em 2d, como mostrado acima.
Somente retângulos totalmente preenchidos são considerados para a contagem.
Os retângulos devem ser cercados por zeros, a menos que estejam na borda (os retângulos que tocam na diagonal dos zeros são válidos (veja o exemplo)).
Por exemplo, na matriz acima, existem 5 retângulos válidos.
Você pode usar qualquer idioma.
