    Default Need help with understanding recursion.

    Hello Everyone,

    I just wanted to know if anyone can help me understand a recursion problem. I'm trying to create a recursion method. My professor wants to me find the number of times a specific character, or set of characters appears in the name of a word. I actually understand the topic but I don't know where to begin with this problem. Can anyone help me?

    Please write code based on your algorithm. If you face any problems with code do post here to get advice.

    Hello dineshj83,

    Thank you for the quick response. To be honest with you I don't know how to approach this problem. I understand the overall concept but writing the code has been a bit of challenge for me. I will tell you want I know.

    I know that I need to find how many times specific character or set of character appear in my word.
    i.e Google
    G - 1
    o - 2
    g - 2
    l - 1
    e - 1
    go - 1
    goo - 2
    goog - 1
    ...
    ...
    ...
    etc etc

    I know a recursion method would work in the case.


    public static String angaram(String anagram){

    if (sometype of variable == 1)
    {
    ...
    ...
    ..

    }
    else
    {
    ...
    ...
    ..
    return something * ....
    }

    }


    I know my method is pretty rough but I'm trying here. I'm asking anyone to do my work. I just would like to pointed or maybe be explained on where I might I want to start off. My professor said if you understand recursion you should't have a problem with this problem. I think I understand recursion?

    For identifying number of characters repeating in a given word you don't have to recurse instead you need to loop through the string for each character. I hope this algorithm helps you to write code.

    My professor wants us to use recursion. We can use for loops to go through my array but not evaluating the String.
