  #include <bits/stdc++.h>
  using namespace std;
  int x;
  int main(){
      cin >> x;
      cout << x << endl;
      cout << "Hello World !" << endl;

  def isvalidinput(x: int) -> bool: return 1 <= x <= 10**9

  def solve(): try: x = int(input()) if not isvalidinput(x): raise ValueError print(x) print("Hello World !") print("28tech C++ programming !") except: pass

  if name == "main": solve()
