JAVA. Trying to create a LinkedListStack to solve a mathematical expression.. Issue with the variable types

Asked 2021-Mar-08 at 00:48

JAVA. I am trying to create a LinkedListStack to solve a mathematical expression. Ex: (1 + 2) * 4 - 3. I am having trouble with the different variable types saying that they are incompatible. There is an issue with the pop and peek methods I wrote and I cannot figure out how to get them to work. I cannot use the Java LinkedList or Stack classes, so I had to write the LLNode class and LinkedList class. Here are the errors I am getting:

I think the problem has to do with your thinking about the stack itself.

You don't have a one stack for operators and another for operands.

It's one stack for the whole thing.

QUESTION

Why does the `search` function doesn't run?

Asked 2020-Nov-25 at 08:48

I wrote a function to search nodes in a singly linked list. When I run it, it gets stuck while printing the node does or doesn't exist. There's no warning in the code so I am wondering if there's something wrong with my concept of function calls.

I know that curr->CharArr[9] shouldn't be in the function call, but what should I replace with it if I don't use it? Or is it actually acceptable?

This is the function call for searching nodes.

LinkedList .equals vs == operator on Integers

Asked 2020-Nov-23 at 22:27

I'm debugging this contains method for a LinkedList that I coded and the comparison of the Integer type 30 is not getting caught in the contains method. From my understanding, the == operator is used to compare addresses in memory and the .equals operator is used to compare equivalency. I have messed around a bit and can't seem to find out why comparing the Integer value of 30 that is passed into the contains method it is still not catching an Integer 30 that was added with the add method when entered.

There are some problems in your code. Apart from not setting curr->left values. I think the way you're iterating over your linked list; head would be NULL at the end of first iteration and control won't come inside reverse printing loop. You would need to break out of loop without moving the head when you reach curr->left == NULL or curr->right == NULL depending upon you're traversing forward or backward.

I made some code changes to your code and I was able to see desired output:

You are allocating an LLNode and assigning it to tmp. Then tmp is assigned to pos. What happened to newly allocated LLNode? It is leaked.

Updating LinkList index's after remove

Asked 2020-Oct-22 at 20:07

I'm practicing with LinkLists and trying to make a remove method from scratch that removes the node in the linked list and also updates index values that I have associated with each node. I have tried some logic for different cases but they don't seem right. The node index updating for each case doesn't seem right either.

ANSWER

Answered 2020-Oct-21 at 05:58

As I'm seeing, that is a double linked list. As is suggested in comments, avoid using an index as part of the node itself, the index is part of the List, because the list controls the way each node is traversed to perform any operation (add, remove, find, etc)

My suggestion (for sublist):

Check if the sublist is within the size of your list (you can throw some exception or return some default data, it depends on your design)
Move the index control to the list
For getting the sublist, you might have something like get the start node of the sublist, and then, use the nextPointer to traverse through the next nodes. You can calculate the size of the sublist and use that to control when you have to stop

Did i correctly implement the recursive add function? My front node is remaining null

I am supposed to implement a recursive linked list, but after writing the code and debugging, it seems that my front node is remaining unchanged (it is staying at null). Any help will be appreciated.

ANSWER

Answered 2020-Sep-07 at 20:45

According to your add method, you try to append the new node from the front-node. In your recursion if you check for node being null, this can only happen if front is not set. You try to set node = newNode, but because java is always pass-by-value the reference to front is never set.

Install llnode

Start an LLDB session with the llnode plugin automatically loaded:.
Never install llnode with sudo as it can easily lead to errors during installation and execution.
For more details on starting llnode see the Usage section.
To get started with the llnode commands see the Commands section.
To use llnode you need to have the LLDB debugger installed. The recommended version is LLDB 3.9 and above.
OS X/macOS You can install Xcode and use the LLDB that comes with it. Optionally, you can install newer versions of lldb using Homebrew with brew update && brew install --with-lldb --with-toolchain llvm and make sure /usr/local/opt/llvm/bin gets searched before /usr/bin/ on your PATH. llnode will link to the LLDB installation returned by llvm-config if available.
Linux You can install the lldb package using the package manager of your distribution. You may need to install additional packages for liblldb as well. For example, on Ubuntu 16.04 you can install the prerequisites with apt-get install lldb-4.0 liblldb-4.0-dev
FreeBSD # Install llvm with lldb and headers pkg install llvm39 rm -f /usr/bin/lldb ln -s /usr/local/bin/lldb39 /usr/bin/lldb
Windows You can install a binary distribution of LLVM directly or using Chocolatey: cinst -y visualstudio2017buildtools visualstudio2017-workload-vctools llvm git Visual Studio is required for MSBuild and headers when building llnode. Git is required to download the lldb headers.
Android / Termux (Experimental) Install Termux (https://termux.com) Install Termux Packages pkg install clang lldb lldb-dev make pkg install nodejs-lts nodejs-lts-dev To debug: llnode -- /data/data/com.termux/files/usr/bin/node --abort_on_uncaught_exception script.js (llnode) run
If you have lldb available on your PATH, simply run:.
Similar to the ~/.lldbinit approach, this way LLDB will also load the plugin automatically on start-up. Doing this may require additional permissions to be able to copy the plugin library to the system plugin directory.
The easiest way to build the plugin:.
