31.1.3.Sort vector1 using make_heap and sort_heap

#include <iostream>

#include <cassert>

#include <algorithm>

#include <vector>

using namespace std;



int main()

{

  vector<int> vector1(5);

  for (int i = 0; i < 5; ++i)

    vector1[i] = i;



  // Shuffle the elements again:

  random_shuffle(vector1.begin(), vector1.end());





  make_heap(vector1.begin(), vector1.end());

  sort_heap(vector1.begin(), vector1.end());



  // Verify that the array is sorted:

  for (int i = 0; i < 5; ++i)

     cout << vector1[i];



  return 0;

}
