Given an input string, reverse the string word by word.For example,Given s = " the sky is blue ",Return " blue is sky the ".Click to show Clarification.Clarification: what constitutes a word? A sequence of non-space characters constitutes a word. could the input string contain leading or trailing spaces? yes. However, your reversed string should not contain leading or trailing spaces. how about multiple spaces between? reduce them to a single space in the reversed string.
