Is this, what you are looking for?

string value="abc";
string result=string.Empty;

for(int i=0;i<=value.Length-1;i++)
{
result+=value[i].ToString()+"\n";
}

for(int i=0;i<=value.Length-1;i++)
{
if(i

Homework question? Should the output contain ACB? or strictly ordered?

Estys

A double iteration over the input string with position and substring length :

        string str = "anystring";

        for (int x = 1; x <= str.Length; x++) // x = substring length
        {
            for (int y = 0; y <= str.Length - x; y++) // y = start position
            {
                Console.WriteLine(str.Substring(y, x));
            }
        }

Cheers

Hello Estys, Thanks for your solution.But it is missing values. Input : ABC Output : A B C AB BC CA // Missing Value SO pls provide the solution for that.

The Length of value is not fixed for 3 it can be increase and the result will be change according to input. then how can i do that.

If you can think then I Can.

Length of string is dynamic too on my example. Did you try my code to see result? Which is result for you if the string is "abcd"

I didn't see the "CA" value, ouch! Can you give an example of the expected output if the input is "ABCD"? Or perhaps describe the situation in words? I suspect you're going to need some recursive algorithm. Cheers

I found some good links : 1. http://n1b-algo.blogspot.com/2009/01/string-permutations.html[^] 2. http://geeksforgeeks.org/?p=767[^] 3. http://stackoverflow.com/questions/361/generate-list-of-all-possible-permutations-of-a-string[^] Hope this helps. All the best.

But he isn't asking for permutations..

CA wasn't in the initial spec, but AC was. The OP needs to better define what the problem actually is (and why he wants to solve it beyond 'my homework says so').

the result by program is : a b c d ab bc cd abcd But Required result is : a b c d ab bc cd da bd abc bcd dab .... abcd ..etc

You're right of course from a professional viewpoint. Some people, non-native english speakers, have trouble finding the right phrasing of the question though, which leads to this kind of confusion. I took a look at his profile, very interesting. Personally, I usually like solving these kindergarten puzzles, even if it sounds like homework :) . Cheers

Backtracking . You can search google to more detail . I can it useful for you . Thanks !!

Maybe this[^] will help.

What you're looking for is the power set of "abc" (http://en.wikipedia.org/wiki/Power_set[^] ) If you go through all the 3-bit numbers (000, 001, 010, 011...) (i.e. the power set) and use the letters corresponding to 1's, that will give you all the permutations.

Based on his/her profile description, he/she should be able to solve that problem.

I think he is asking combination.....
