This is a repository where I collect my code solucions from LeetCode. My profile on LeetCode (if you want to see how active I'm on this platform 😁 PS: not very active).

This README file contains description about how to work with this repository. If you are in search for how to use the final product (website/documentation), how easly navigate throw them, watch intro.

npm install

npm start

This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.

npm build

This command generates static content into the build directory and can be served using any static contents hosting service.

npm run deployOnGitHub

If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch. If firstly so push and secondly deploy, in gh-page will push a commit linked to the last commit from the main branch of the repository, otherwise will be linked to a commit internal for this branch.

Path docs/ contains all files that are used to create documentation (pages with condition and solution).

To add new condition you need to create a file in docs/__condtions/ with name which is used in URL of the page on LeetCode with problem which you want to insert in this project (ex. https://leetcode.com/problems/**contains-duplicate**/ - condition's name will be contains-duplicate) Use .jsx for file's extension. The pattern to use:

import React from 'react';

export default () => (
	// copy-paste the condition here
);

After file was created, copy-paste previous pattern without saving changes. Now you need to copy-paste condition's code and refactor it following this steps:

1. Copy content inside of div with same class: class="content__u3I1 question-content__JfgR" - in result you will have in clipboard a div with others tags.
2. Paste this content instead this comment: // copy-paste the condition here.
3. Remove all <p>&nbsp;</p>.
4. Before same lines: <strong>Output:</strong>, need to paste tag: <br/>
5. Where is used this mathematical signs: <, >, replace them with: < and &mt; respectivly.

Yes, this method is a bit sophisticated, especially to automate this process, a special page has been created, the instruction is here.

Before to create a file with solution, you need to understand which pattern you used, read here.

After you understand the pattern to which your solution refers, open/create the folder corresponding to the pattern. Create a file whose name satisfies the next pattern: task's name.solution.pattern.mdx. Task's name is taked from URL of the page on LeetCode with problem which you want to insert in this project (ex. https://leetcode.com/problems/**contains-duplicate**/ - task's name will be contains-duplicate). The pattern used was determined when you decided in which folder you would create the solution file.

The next steps are easier than the previous ones 🙂

1. Insed of file use this pattern for first line: ```language in which is wrote solution's code.
2. In the third line write: ```.
3. In the second line copy-paste solution's code.

Next to the file with the solution we want to display in the "documentation", we create a file with the name: task_name.mdx.

Condition's title - condition's title looks like this: 217. Contains Duplicate. If it is not clear, open taks's page on LeetCode, in browser's console use this command: document.querySelector('[data-cy="question-title"').innerText - in console will apeare a string which contains what I call "condition's title".

Condition's level - easy | medium | hard. Inside of Task's page will need to use special sign. Type of sign is indicated in the root file .env in parrameter CONDITION_LEVEL_TYPE. After you saw "signs' type", watch the file server/utils/level_signs.json and pick singe which is asociated for level of your condition's level.

1. First line will contains: condition_title condition_level_sign.
2. Import condition and solution like components. Naming will be respectivly: Condition and Solution
3. Write a header of level 2 in markdown's style. Content: Condition. Below, insert <Condition/>
4. Write a header of level 2 in markdown's style. Content: Solution. Below, insert <Solution/>

Path for this file: docs/arrays/contains-duplicate.mdx

# 217. Contains Duplicate 🔵

import Condition from './../__conditions/contains-duplicate.condition';
import Solution from './contains-duplicate.solution.arrays.mdx';

## Condition

<Condition />

## Solution

<Solution />

1. Open sidebars.js.
2. Find the object which is assigned for the category where you want to display the task.
3. In field items of this object, insert a string which represent path to file which represent web-page of the task.
