EN

    // Create new 6 Pot
    val list = mutableListOf<Int>()
    val pot = listOf<Pot>(Pot(50), Pot(50), Pot(50), Pot(50), Pot(50), Pot(50))
    val linearLayout: LinearLayout = findViewById(R.id.text)
    linearLayout.removeAllViews()
    // random 6 number from 1 - 50 without duplicate
    // Create textview to print out roll result

    pot.forEach {
        val d = it
        val rollResult = d.roll()
        list.add(rollResult)
        val textView = TextView(this)
        textView.append(this.toString())
        val param = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT)
        param.marginStart = 10
        textView.layoutParams = param
        textView.text = rollResult.toString()
        linearLayout.addView(textView)
    }
