string permutations with multiple string words

Question

I would like to generate permutations of string words that are inputted from a file. I know the count and was wondering if there is an easy way to do this using an arraylist.

Answer 1

Since this doesn't have a homework tag, I'd suggest using a std::vector of words and std::next_permutation. (If it had a homework tag, I'd suggest how to implement something like std::next_permutation.)

Answer 2

Great article on MSDN Magazine: String Permutations

Combination Generator in Linq (this one has a LINQ based answer)

Using the code provided in the above link:

string str = "leniel";

var permutations = GetPermutations(str);

foreach (string s in permutations)
{
    Console.WriteLine(s);
}

Console.WriteLine(permutations.Count()); // 720 permutations

Console.ReadLine();

Is there a .NET library that can do string permutations or string expansion?
