#include<iostream>
using namespace std;
 
string FirstAndLast(string str)
{
 
 
 string ch = str;
 for (int i = 0; i < ch.length(); i++)
 {
 
 
 int k = i;
 while (i < ch.length() && ch[i] != ' ')
 i++;
 
 
 ch[k] = (char)(ch[k] >= 'a' && ch[k] <= 'z'
 ? ((int)ch[k] - 32)
 : (int)ch[k]);
 ch[i - 1] = (char)(ch[i - 1] >= 'a' && ch[i - 1] <= 'z'
 ? ((int)ch[i - 1] - 32)
 : (int)ch[i - 1]);
 }
 
 return ch;
}
 
 void empty(string s){
 if(s==" "){
 cout<<"The string is empty\n"; 
 }
 }
string removeWord(string str, string word) 
{
 
 if (str.find(word) != string::npos)
 {
 size_t p = -1;
 
 
 string tempWord = word + " ";
 while ((p = str.find(word)) != string::npos)
 str.replace(p, tempWord.length(), "");
 
 
 tempWord = " " + word;
 while ((p = str.find(word)) != string::npos)
 str.replace(p, tempWord.length(), "");
 }
 
 
 return str;
}


int main()
{
 cout<<"Enter a string: \n";
 string na;
 getline(cin,na);
 cout<<FirstAndLast(na)<<endl;
}
