Hello Folks,

Can you help me how to find out unique combination of digits for 1-99 digits eg.

{1, 2, 3, 4}

But the combination should be unique using C# language.

Can any body give me any hint. I know how to find combinations, but the problem is how to find unique combination only.

Thanks

Not clear. The requirements should be mathematically precise. Which combinations you define as different or equivalent? Also, explain what is your problem?

C#

for(int a = 1; a < 97; a++)
  for(int b = a + 1; b < 98; b++)
    for(int c = b + 1; c < 99; c++)
      for(int d = c + 1; d < 100; d++)
        Console.WriteLine( a.ToString() + " " +
                           b.ToString() + " " +
                           c.ToString() + " " +
                           d.ToString());
