Cover script with tests

Add frequency

Hey @prius would it be possible to get the frequency of a problem as a tag in anki? This would make it a lot easier to prioritise canonical problems.

Thanks I really love this tool!

Cards are generated with "No content" for some leetcode problems

For a small subset of questions, the generated cards don't capture the question content but instead, have the Content field being No content.

For instance, problem 2340 has such an issue deterministically, while problem 2341 always shows up fine.

Some Leetcode questions with Content field being no content:

• 2339
• 2340
• 2345
• 2346
• 2355
• 2356
• 2361
• 2362
• ...

Split the script into files

Now when it works, it's time to make it look nice as well.

So we need to split the script into files and make a nice CLI for that.

Create cards with Solution/s on Back (in chosen langs)?

I love this, but I expected it to fetch solution information/strategies and actual solution code in various languages.

Is there an easy way to edit this to get a deck with cards with the problems on the front and tons of solution info on the back? (Maybe with fields for solution/s and strategy/ies descriptions and solution lang fields like python, java, typescript, etc,. and maybe even including a field about which lang is fastest)

I am looking for a way to use Anki to memorize all the problems AND their solution/s, not just what the problems are. I feel this would be a quicker way to learn. Any ideas? Could you point me in the right direction?

Release is missing the leetcode.apkg file content

When a new release is created via GitHub actions, the leetcode.apkg file is visible in the assets and has a size, but its content is missing (GitHub returns 404 when you try to download it).

An example: https://github.com/prius/leetcode-anki/releases/tag/refs%2Fheads%2Fmaster-1635295155

I tried to fork the repo and create a new release myself but ended up with the same issue: https://github.com/dropsonic/leetcode-anki/releases/tag/refs%2Fheads%2Fmaster-1676754546

The Build Anki deck workflow doesn't show any errors. The "Upload release asset" step succeeded without any errors.

Investigate a possibility to issue batch requests to leetcode

It is possible to issue batch requests to the leetcode API. The current method is super slow. There are graphql queries that allow you to fetch many problems at once. But they should be implemented in the python-leetcode library first.

Add hints to flashcrads

Might be useful

1 card is missing during deck generation

Leetcode return tehre are 2052 cards, but we get 2051 in the end. It is either a bug with the way we calculate pages and offsets, or leetcode really returns incorrect number of problems. Have to investigate

Any way to order the problems?

I've found the most helpful thing for me so far is using curated/organized lists, like this one.

I started manually making cards and it is a pain, so your tool seems great! But I am concerned if Anki is just going to randomly throw all 25XX problems at me, it won't be as effective.

Is there any way (via this or in Anki) to encourage/constrain the cards or their ordering?

Sort field doesn't work

I set the sort field to 3 digits string at the moment: https://github.com/prius/leetcode-anki/blob/master/generate.py#L298

But the sorting is still incorrect.

For example, there are 15 cards for which sorting by the sort field gives the following order:

012
010
025
011
023
006
002
035
008
033
036
037
037
011
048

So effective there is no sorting.

I guess I need to look at Anki's source code to understand how it uses this field.

Error when trying to run `make generate`

Hello, I'm on a Mac running Python 3.11.1 and receiving an error when running the make generate build script.

Below is an output from CLI

Any suggestions on how to fix this? I have followed the README steps to a T.

How to add solutions?

This repo is really awesome and just what I was doing for myself.
I just have a question about adding my own solutions to the "back" card. I managed to add the field but it's not the back. And I don't see the discuss and solutions card.. could you help me with this?

Would it be possible to create flashcards only for a specific set of problems, for example the top 150 interview questions.

This is due to logic change

too confusing to use

can you make more documentation on how to actually use this?
