Given a string, you need to reverse the order of characters in each word within a sentence while still preserving whitespace and initial word order.
Example 1:
Input: "Let's take LeetCode contest"
Output: "s'teL ekat edoCteeL tsetnoc"
Note: In the string, each word is separated by single space and there will not be any extra space in the string.

我的代码：
class Solution {
public:
string reverseWords(string s) {
string ss,temp;
int k=0;
for(int i=0;i<=s.size();i++)
{
if(s[i]==' '||i==s.size())
{
temp="";
for(int j=i-1;j>=k;j--)
temp+=s[j];
if(s[i]==' ')
ss+=temp+" ";
else
ss+=temp;
k=i+1;
}
}
return ss;
}
};
