T1: Number theory + high precision (water ~)

According to the question, the bigger the number of division, the better (in the range of 0 ~ 9)

So we only need to use high-precision division and then simulate it.

// MARK: However, note that the special value 0-9 requires special determination. Because the output number of the question must be at least two digits, 1 should be added before the 0-9 output. if 1 should output 11 instead of 1;
