import java.util.ArrayList;
import java.util.List;

public class MyClass {
    public static List<String> split_string_into_3_word_lines(String str) {
        String[] words = str.split(" ");
        List<String> threeWordLines = new ArrayList<>();
        
        int length = words.length;
        for (int i = 0; i < length; i += 3) {
            StringBuilder oneline = new StringBuilder();
            for (int j = i; j < Math.min(i + 3, length); j++) {
                oneline.append(words[j]).append(" ");
            }
            threeWordLines.add(oneline.toString().trim());
        }
  
        return threeWordLines;
    }
    
    public static void main(String args[]) {
        String str = "java c c++ python rust go php typescript";
        
        List<String> threeWordLines = split_string_into_3_word_lines(str);
        
        for (String line : threeWordLines) {
            System.out.println(line);
