How to reseting int ??

hy, i have question : how to resetting int,
i make combo button, but when i press button again and again, it can’t to attack anymore until i stop press button and always wait for int time. so i need to make when i press button again and again, the int can resetting to 0 automaticly and faster.
this my script :

        int noOfClicks = 3; //i mean this int
	float lastClickedTime = 0.25f;
	float maxComboDelay = 0.5f;

        void Update()
	{
		if (Time.time - lastClickedTime > maxComboDelay) 
		{
			noOfClicks = 0;
		}
         }

public void OnClick()
	{
		lastClickedTime = Time.time;
		noOfClicks++;

		if (noOfClicks == 1) 
		{
			animatio.SetBool("Atk4", true);
		}

		if (noOfClicks >= 2) 
		{
			animatio.SetBool("Atk4", true);
		}

		if (noOfClicks >= 3) 
		{
			animatio.SetBool("Atk4", true);
		}

		if (noOfClicks >= 4) 
		{
			animatio.SetBool("Atk4", true);
		}

		noOfClicks = Mathf.Clamp (noOfClicks, 0, 4);
	}
//So how i can to stop int automaticly when i press fourtime, i need int back to 0 automaticly, more fater and ready when i press button again.

Is this what you mean?

         if (noOfClicks >= 4) 
         {
             animatio.SetBool("Atk4", true);
             noOfClicks = 0; //Add this
         }
