Test instructions: The words in the string are sorted in reverse order, with a space in the middle of each word, with no spaces in front of the strings and at the end of the string. The order of the words is not changed, but the order of the words in the string is changed.

Idea: Filter the front and back of the string, with the pointer to the previous sweep, and then a temporary string to save the word, full of a word will be added in the end of the string in front. After sweeping the string, the final string is assigned to S.
