Thanks you

Answer 4

My input: There are multiple groups of input. Each group has a number not more than 5 digits
My output:
For each input number, output according to three lines:
Number of digits in the first row
Separate each digit with a space on the second line, note that there is no space after the last digit
The third line outputs this number in reverse order.
For example, when I input "12345" the Output will be
5
1 2 3 4 5
54321
But my output is
5
12345(How to add space here?)
54321
