Nothing today, I remembered two programs that were impressed when I was studying in the school: Print 99 multiplication table and the solution of 9 palace. 99 Multiplication Table, let me know that the original For can also be used in two layers; the one of the 9 palace pictures, the time written is a 4x4 (in actually 16 palace), running on the school's broken machine 2 minutes More, I got a few thousand solutions; remember Zhang Shaishu (嘿, don't hit me) I don't believe there have so many results. Oh, I haven't been there for a long time. Miss life in school! I miss the day of playing the Red Police Warcraft, playing football!
