#include <iostream>
#include <string>

using std::cout;
using std::endl;
using std::string;

// Function to remove the first word (up to first space or tab)
string TrimFirstWord(const string& input) {
    size_t pos = input.find_first_of(" \t");
    
    if (pos != string::npos)
        return input.substr(pos + 1);
        
    return input; // return original if no space or tab found
}

int main()
{
    string s = "c++ c c# java php";

    s = TrimFirstWord(s);

    cout << s << endl;

    return 0;
