  int default_value = 1;
  // first initialize a vector of ints with given default value
  std::vector<int> v(N, default_value);
  // Use above vector to initialize the two-dimensional vector
  std::vector<std::vector<int>> matrix(M, v);
 
  // This vector initializes with the values: 10, 20, and 30
  vector<int> vect{ 10, 20, 30 };
