1. Login to Leetcode and get LEETCODE_SESSION cookie

Login to Leetcode and follow these steps

1. Open devtools and go to Applications tab
2. Go to cookies
3. Get the value of the cookie whose key is LEETCODE_SESSION

2. Make your list where you want to collect the bookmarked problems into

2. Click the `+` button next to the text *My List* and create your new list

3. Get the list of problem links

You need a text.txt file that contains a list of problem links. The logic inside app will automatically extract the https links, so make sure that your text file contains only links that is a valid leet code problem.

For example this is valid text file.

Hello,
I have been solving all two pointers tagged problems in last 3.5 months, and wanted to share my findings/classifications here. If you are preparing for technical interview, two pointers is one of the popular topics that you can't skip :).

There are around 140 problems today, but I only solved the public ones (117 problems).
Majority of them is in easy or medium so, if you understand the basic ideas then it should be solvable without much hints and editorials.

I see 4 bigger categories and many sub categories in it, and marked the typical example problems with (*).
I would recommend you to start solving these example problems, and apply the knowledge to the other problems. I don't want to copy & paste my ugly codes here, you would easily find fantastic solutions from the problem discussion page.


1. Running from both ends of an array
The first type of problems are, having two pointers at left and right end of array, then moving them to the center while processing something with them.

After you've got proper list of links, save it as text.txt file into the project root!

Execution

Execute this CLI command in the project root.

python app.py

or

sudo python app.py

The CLI will ask you three inputs; leetcode-session-token, listname, action

For leetcode-session-token, copy and paste the cookie value you've got

For listname, type the name of the list you want to collect the problems into

For actions, type Add if you want to add the problems into the list or type 'Remove' if you want to remove the problems from that list

For example, this command will let the app to login to Leetcode via $sample-values$ and then add problems into $sample-list$

sudo python app.py
Password:
leetcode-session-token: $sample-value$
listname: $sample-list$
action ( Add / Remove ): Add
