题目

有如下VB程序段： k = 0 For i = 1 To 10     If b(a(i)) = 0 Then k = k + 1     b(a(i)) = b(a(i)) + 1 Next i For i = 1 To k     p = 1     For j = 2 To 10        If b(j) > b(p) Then p = j     Next j     b(p) = 0     s = s + Str(p) Next i 数组a(1)～a(10)的元素分别为2,5,3,8,8,5,8,9,5,3。数组b(1)～b(10)的元素初始值均为0，执行程序后，变量s的值为（   ） A . " 5 8 3 2 9" B . " 2 3 5 8 9" C . " 8 5 3 9 2" D . " 2 9 3 5 8" 答案：A
