Try to study and understand the code first.Where is your ListNode class? So u dont know the “new list node(0)” is instance of a class called list node which might be an implementation of a linked list. So where is the class?

I actually copied the code. What I am saying is that for the exact code to run on leetcode and not run on an ide is something else. This same code is working without listnode class being define on leetcode that is why I was asking.


However Tensa comment has helped to clarify me

It is not defined because you haven't created the linked list data structure. You are running it outside leetcode which gives you the data structure defined.

Thank you

Front end is beyond data presentation or simply designing of nice interface. Font end can be complex if for example it has to process data from an api, renders it and send it back to the api or another api. That does not mean it is difficult or more easier. The complexity depends on the project at hand and where the business logic lies. Why some may claim it is wrong for the business logic to be handle by the front end, I doubt if there is any professional reason why it should not because there are times where you don't even have access to the server at the first instance

HTML, css, php, JavaScript, Vue, Laravel

After the User is done with payment process on Paystack (successful or not) the call back url is the url user will be redirect to. On this page you might want to display success or fail message depending on the status of transaction.

The charge.success is an event you might want to listen for, this is useful if you have other operations that need to be complete for a successful transaction.

For verify transaction: let's say your website give access to some paid content, after payment you will want to verify if that particular transaction is valid by comparing the payment ref on your local db with reference on Paystack, If the transaction is successful, if the right amount was paid etc

1a properties are the variables in a method while method are the function use to manipulate these variables. for instance you could have a function that sum two numbers. the two numbers are the variable also known as properties while the function that actually performs the addition is known as method....function add(){x+y}

2b: event take place whenever a user interacts with you program.it could be a simple click on a checkbox,mouse over, key press etc. while event handlers capture the action and triggers an appropriate response. a simple event could be something like a tick on a checkbox while the handler could disable the submit button once the event is performed

3b: conceptualize a class as a collection of things and an object as part of the things also as instance of a class. an object is part of a class while a class is the container or house of an object also known as the blueprint of an object.
