// C++ code to demonstrate the working of
// partition() and is_partitioned()
#include<iostream>
#include<algorithm> // for partition algorithm
#include<vector> // for vector
using namespace std;
int main()
{
    // Initializing vector
    vector<int> vect = { 2, 1, 5, 6, 8, 7 };
     
    // Checking if vector is partitioned
    // using is_partitioned()
    is_partitioned(vect.begin(), vect.end(), [](int x)
    {
        return x%2==0;
         
    })?
     
    cout << "Vector is partitioned":
    cout << "Vector is not partitioned";
    cout << endl;
     
    // partitioning vector using partition()
    partition(vect.begin(), vect.end(), [](int x)
    {
        return x%2==0;
         
    });
     
    // Checking if vector is partitioned
    // using is_partitioned()
    is_partitioned(vect.begin(), vect.end(), [](int x)
    {
        return x%2==0;
         
    })?
     
    cout << "Now, vector is partitioned after partition operation":
    cout << "Vector is still not partitioned after partition operation";
    cout << endl;
     
    // Displaying partitioned Vector
    cout << "The partitioned vector is : ";
    for (int &x : vect) cout << x << " ";
     
    return 0;
     
}
