    Solved it :)

    Many thanks Norm for you patience and time. I have changed various values in the file to make different animals have the biggest value and it has returned the correct maximum every...

    Re: find largest value in BST

    The way I am seeing it is that the returned value is used but that it is incorrect because inorderHelper() is obviously not right yet and I still need to solve that.

    Re: find largest value in BST

    I took out the unnecessary args. I kind of made the situation worse trying to find a way to get it right and more variables crept in that were not needed.

    The only time it could have returned 0...

    Re: find largest value in BST

    I have edited the code in post #3 to match my latest testing on it. I am a bit rushed so will mention more about this on my return home.

    Basically the max value is wrongly adjusted to a lower...

    Re: find largest value in BST

    I will pick this up again tomorrow afternoon. I think I might just get it. I almost want to keep at it now, but I need to do other things for now.

    To update, I have added a variable as an...

    Re: find largest value in BST

    I have been trying to not use global variables which is the only other way I can see ... so far. I know I must be missing something that once I know it I will know forever, but I just cannot see it...

    Re: find largest value in BST

    The method returns the root's attribute which is frustrating me. Also, to store it in a variable, the variable needs initialising and therefore it will just default to the initialised value when the...

    Re: find largest value in BST

    Basically the x and y variables were just done for quickness when trying out my idea and checking what is going on. The names you suggest are essentially what they represent. I have tried to avoid...

    Re: find largest value in BST

    Thanks for your time with this Norm. For now I have to rest and sleep so I will try again tomorrow.

    I cannot work out the toString() method still. But my main issue here is how to get it to return...

    Re: find largest value in BST

    I haven't done the toString() method in the Node class, mainly because I haven't worked out what you meant yet (I will probably realise in the morning after I have slept but I doing what I can while...

    Re: find largest value in BST

    I have made a file which shows the output I am seeing (attached to this post).

    I have also edited the code in post #3 which should be exactly the same as what I am using at the moment

    Re: find largest value in BST

    It is in post #3

    I have also edited it to have the file I am currently working from in the same thread.

    Maybe I should have edited the code there also.

    I am still stuck with this. Whilst I said I can see why my previous effort is failing, I still have not found a way to get this right.

    Re: find largest value in BST

    I realised it was not checking all the nodes when I looked for an explanation for it returning the wrong value. My first effort to put it right so it searches all nodes caused it to just return the...

    I found using a print statement very useful in helping me to get to the solution of another method that had been troubling me. I pretty much understand why it is not returning the correct value in...

    It reads the file fine. It is the method that the problem is with. I have made a dummy file and added it to the post. It will probably not have the same result because the data is different, but the...
