`[0, last - first)`, the predicate `comp(*(first + N))` is true.

### Example

```cpp
// alg_any_of.cpp
// compile with: /EHsc
#include <list>
#include <algorithm>
#include <iostream>

int main()
{
using namespace std;

list<int> li { 51, 41, 11, 21, 20 };

cout << "li = ( ";
for (auto const& el : li)
cout << el << " ";
cout << ")" << endl;

// Check if there is an even elememt in li.
auto is_even = [](int const elem){ return !(elem % 2); };
if (any_of(li.begin(), li.end(), is_even))
cout << "There's an even element in li.\n";
else
cout << "There are no even elements in li.\n";
}
```

```Output
L = ( 51 41 11 21 20 )
There's an even element in li.
```
