HDU1062 Text Reverse (simple string processing)

Idea: Reverse the output of each non-space character string separated by spaces. Pay attention to the last one to reverse and read in.
Skill: You can use getline to read in a character string with spaces, and you can use STL's reverse function. Reverse the string
