有六位数,第一位和最后一位互换,原来的六位数是新的六位数的五倍,求是那六位数是

Dim x As Long
Dim y As Long
For x = 100001 To 999999
y = x Mod 10
If (x - y) / 10 + y * 100000 = x / 5 Then
Print x
Exit Sub
End If
Next

结果是，不存在该数

174998
int num = 0;
int num2 = 0;
for (int i = 100000; i < 999999; i++)
{
num = i;
try
{
string num1 = i.ToString();
string[] array = new string[num1.Length];
for (int j = 0; j < num1.Length; j++)
{
array[j] = num1.Substring(j,1);
}

string str="";
str+= array[5].ToString();
str += array[1].ToString();
str += array[2].ToString();
