就是给出一个整数，将它的因子通过模拟七段管显示出来

    // 10,5 3

    static String[][] dict = new String[][] {

        { " - ", "| |", "   ", "| |", " - " },  // 0

        { "   ", "  |", "   ", "  |", "   " },  // 1

        { " - ", "  |", " - ", "|  ", " - " },  // 2

        { " - ", "  |", " - ", "  |", " - " },  // 3

        { "   ", "| |", " - ", "  |", "   " },  // 4

        { " - ", "|  ", " - ", "  |", " - " },  // 5

        { " - ", "|  ", " - ", "| |", " - "},   // 6

        { " - ", "  |", "   ", "  |", "   " },  // 7

        { " - ", "| |", " - ", "| |", " - " },  // 8

        { " - ", "| |", " - ", "  |", " - " } };// 9
