C Sharp Combination

[cubanoemg]

Hi everyone

I'm trying to create all possible combinations without repetitions.

I need to create 3 numbers with values from 1-10 with no repetitions.

Ex: 1-2-3
1-3-4
1-2-4
1-3-5
2-3-5
and so on..... I need a loop or something to create all this and fill a 2d array[120,3]

using System;
class Program
{   
    static void Main()   
    {
            int[][] data = new int[120][];      
        int index = 0;                
        for ( int a = 1; a <= 8; ++a )      
        {         
            for ( int b = a + 1; b <= 9; ++b )         
            {            
                for ( int c = b + 1; c <= 10; ++c )             
                {               
                    data[index++] = new int[] { a, b, c };         
                }        
            }     
        }     
        for ( int i = 0; i < 120; ++i )      
        {        
            Console.WriteLine("{0:D3} -> {1}-{2}-{3}", i + 1, data[i][0], data[i][1], data[i][2]); 
        }      
        //Console.Read();  
    }
}

Please don't post full solutions. Bytes is about helping people learn, not simply giving them the answer. When you give the solution the person asking the question typically learns nothing.

Try to help them work through the solution first.
