C#实现的排列与组合(Permutation & Combination)算法

I wrote two generic class to implement these two algorithms, so you can use these classes to generate permutations and combinations for some use, such as software testing.

Using the Code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Collections;

namespace CombinationAlgorithmic

output:

10 Combinations of Array "1,2,3,4,5":

 

1,2,3

1,2,4

1,2,5

1,3,4

1,3,5

1,4,5

2,3,4

2,3,5

2,4,5
