Using Traits in Traits

Traits, like classes, can also use other traits. Let's look at an example. Suppose we have this trait with two methods:

<?php
	trait Trait1
	{
		private function method1()
		{
			return 1;
		}
		
		private function method2()
		{
			return 2;
		}
	}
?>

Suppose we also have another trait:

<?php
	trait Trait2
	{
		private function method3()
		{
			return 3;
		}
	}
?>

Let's connect the trait Trait1 to the trait Trait2:

<?php
	trait Trait2
	{
		use Trait1; // using the first trait
		
		private function method3()
		{
			return 3;
		}
	}
?>

After such a connection, it turns out that Trait2 will have not only its own methods but also the methods of the trait Trait1. Let's test this: create a class Test, connect the trait Trait2 to it, and make sure that our class will have methods from both the first trait and the second:

<?php
	class Test
	{
		use Trait2; // connecting the second trait
		
		public function __construct()
		{
			echo $this->method1(); // method of the first trait
			echo $this->method2(); // method of the first trait
			echo $this->method3(); // method of the second trait
		}
	}
?>

Independently create the same traits as I have and connect them to the class Test. Create a method getSum in this class, returning the sum of the results of the methods of the connected traits.
