// C++ program to reverse individual words in a given  
// string using STL list 
#include <bits/stdc++.h> 
using namespace std; 
  
// reverses individual words of a string 
void reverseWords(string str) 
{ 
    stack<char> st; 
  
    // Traverse given string and push all characters 
    // to stack until we see a space. 
    for (int i = 0; i < str.length(); ++i) { 
        if (str[i] != ' ') 
            st.push(str[i]); 
  
        // When we see a space, we print contents 
        // of stack. 
        else { 
            while (st.empty() == false) { 
                cout << st.top(); 
                st.pop();

            cout << " "; 
        } 
    } 
  
    // Since there may not be space after
