PROGRAMMING:The story of Daben (5) -- confession
Daben is 20 years old. It's time to express her love to the girl she's loved for a long time. Before the confession, Daben superstitiously found the fortune teller Dabu to make a divination. The master pointed to a piece of watermarked cloth and said: "when you return to one array, it's right. If you are even, it can be done.". That is to say, in an n * n (1 < = n < = 50) 0,1 square matrix, the number of 1 in each row and column is even, and the big run can be successful. Then, according to the watermark, can Daben advertise successfully?
