Ti viene fornita una matrice bidimensionale di byte di dimensioni mx n. È garantito che tutti i byte siano 1 o 0. Trova il numero di rettangoli rappresentati da 1 quando visualizzato in 2d, come mostrato sopra.
Per il conteggio vengono considerati solo rettangoli pieni.
I rettangoli devono essere circondati da 0 a meno che non siano sul bordo (i rettangoli toccanti in diagonale di 1 vanno bene però (vedi esempio.)).
Ad esempio, nell'array sopra ci sono 5 rettangoli validi.
Puoi usare qualsiasi lingua.
