What text will appear in the console after running the program

It is necessary to predict what result will be output to the console when executing the following C++ code.

#include <algorithm>
#include <iostream>
#include <list>

bool IsEven(int value)
{
    return value % 2 == 0;
}

void ProcessAndShow()
{
    std::list<int> numbers = {0, 1, 2, 3, 4, 5};
    std::remove_if(numbers.begin(), numbers.end(), IsEven);
    std::cout << numbers.front() << numbers.size() << std::endl;
}

int main()
{
    ProcessAndShow();
    return 0;
}
