Why does this code create an infinite loop?when Instantiate a gameobject and set it parent

Why does this code create an infinite loop? Does it represent one loop when it instantiates a GameObject and then sets its parent?

    public GameObject ui;
    GameObject child;
    private void Start()
    {
        for (int i = 0; i < 10; i++)
        {
            child = Instantiate(ui);
            child.transform.SetParent(ui.transform,false);

        }
    }

>Solution :

Instantiation makes a copy of an object with all of its hierarchy. You’re making copy of ui and assigning it as a child of the original ui object, so your hierarchy now looks like this:

ui (original)
-ui (copy)

In the next iteration of loop ui object is getting cloned again and becomes this:

ui
-ui
-ui (copy of ui with new child)
--ui 

On the third iteration it will be doubled again. See where it is going?
And finally, I assume that your script that copies the ui is… on that ui object, thus is also copied each time, leading to the endless loop.
