Digital reading is as follows:
Every four bits are read as a whole, and the whole four bits are ① the lowest bit, ②20000 bits are the lowest bit, and ③ 300 million bits are the lowest bit.
And the zero at the end of each four-digit integer does not need to be read; If there are two non-zero numbers with two or more zeros in the middle, read only one; If all the digits in the four-digit integer are zeros, read a zero and throw the rest according to the above rules; When there is no zero between four moving people, add a zero.
