1. (2017高三上·温州期中) 【加试题】有如下VB程序段：

For i = 5 To 4 Step -1

        k = i

        For j = 6 - i To 1 Step -1

           If a(j) < a(k) Then k = j

        Next j

        If i <> k Then

           t = a(i): a(i) = a(k): a(k) = t

        End If

    Next i

数组元素a(1)到a(5)的值依次为“41，66，70，83，31”，经过该程序段“加工”后，数组元素a(1)到a(5)的值依次为（  ）
