找鞍点：在一个矩阵中，如果i行上的最大值a(i,j)同时是第j列上最小值，则称该数是一个鞍点。
例如：
1        4        9        8
3        4        6        1
7        5        8        6
在上面的矩阵中，第二行第三列的元素6就是这个矩阵的鞍点。
下面是我写的程序，经过测试，漏洞百出。请大家指点迷津

Private Sub Command1_Click()
Const M As Integer = 3
Const N As Integer = 3
Dim min As Integer
Dim max As Integer
Dim p As Integer
Dim q As Integer
Dim data(M, N) As Integer
Dim i As Integer
Dim j As Integer
Dim k As Integer
Randomize Timer
For i = 1 To M
 For j = 1 To N
  data(i, j) = Rnd * 50
 Next
Next
For i = 1 To M
 For j = 1 To N
  Print data(i, j),
 Next
Print
Next
For i = 1 To M
 For j = 1 To N
  If data(i, j) > max Then
  p = i: q = j
  max = data(i, j)
  End If
 Next
 min = max
For k = 1 To M
 If min >= data(k, q) Then
  min = data(k, q)
  Exit For
End If
Next
If max = min Then
Print "找到鞍点:"; max
Print "其行值为:"; p, "其列值为:"; q
Exit Sub
End If
Next
Print "没找到鞍点"
End Sub

百度一下..太多了.

百度里找的都是C语言C++的程序，看不懂。
