Rust 写了个 leetcode-cli, 诚邀大佬们来体验 🐳

[udtrokia]

本来想老老实实刷下 leetcode 年后认认真真找个工作...结果 20 道没刷够就跑神写了这个 proj，蛮有意思的，参考了 skygragon 大牛的 node 版本，在里面添了个 python 解释器，可以通过 python 脚本过滤题目。

(粘一下 README 过来...)

leetcode-cli

Features

• [x] the edit flow —— solution files will generate automatically!
• [x] support python scripts to filter questions
• [ ] doc support, lc-rs can compile the annotation of your solutions to markdown!
• [ ] support local signal to keep coding as longer as you want.

Building

cargo install leetcode-cli

Usage

Please make sure you have logined in leetcode.com with chrome, more info plz checkout this

leetcode 0.2.6
clearloop <[email protected]>
Here's to the crazy ones 👻

USAGE:
    leetcode [FLAGS] [SUBCOMMAND]

FLAGS:
    -d, --debug      debug mode
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    data    Manage Cache [aliases: d]
    edit    Edit question by id [aliases: e]
    exec    Submit solution [aliases: x]
    list    List problems [aliases: l]

    stat    Show simple chart about submissions [aliases: s]
    test    Edit question by id [aliases: t]
    help    Prints this message or the help of the given subcommand(s)

Example

For example, if your config is:

[code]
lang = "rust"
editor = "emacs"

1. pick

leetcode pick 1

[1] Two Sum is on the run...


Given an array of integers, return indices of the two numbers such that they add up to a specific target.

You may assume that each input would have exactly one solution, and you may not use the same element twice.

--------------------------------------------------

Example:


Given nums = [2, 7, 11, 15], target = 9,

Because nums[0] + nums[1] = 2 + 7 = 9,
return [0, 1].

2. edit

leetcode edit 1

impl Solution {
    pub fn two_sum(nums: Vec<i32>, target: i32) -> Vec<i32> {
        use std::collections::HashMap;
        let mut m: HashMap<i32, i32> = HashMap::new();

        for (i, e) in nums.iter().enumerate() {
            if let Some(v) = m.get(&(target - e)) {
                return vec![*v, i as i32];
            }

            m.insert(*e, i as i32).unwrap_or_default();
        }

        return vec![];
    }
}

3. test

leetcode test 1

  Accepted       Runtime: 0 ms

  Your input:    [2,7,11,15], 9
  Output:        [0,1]
  Expected:      [0,1]

4. submit

leetcode submit 1

  Success

  Runtime: 0 ms, faster than 100% of Rustonline submissions for Two Sum.

  Memory Usage: 2.4 MB, less than 100% of Rustonline submissions for Two Sum.

Cookies

The cookie plugin of leetcode-cil can work on OSX and Linux, If you are on other platforms or your cookies just don't want to be catched, you can handwrite your LeetCode Cookies to ~/.leetcode/leetcode.toml

# Make sure `leetcode.toml` file is placed at `~/.leetcode/leetcode.toml`
[cookies]
csrf = "..."
session = "..."

For Example, if you're using chrome to login to leetcode.com.

Step 1

Open chrome and paste the link below to the chrome linkbar.

chrome://settings/cookies/detail?site=leetcode.com

Step 2

Copy the contents of LEETCODE_SESSION and csrftoken.

Step 3

Paste them to session and csrf.

# Make sure `leetcode.toml` file is placed at `~/.leetcode/leetcode.toml`
[cookies]
csrf = "${csrftoken}"
session = "${LEETCODE_SESSION}"

Programmable

If we want to filter leetcode questions using our own python scripts, what should we do?

For example, our config is:

# Make sure `leetcode.toml` file is placed at `~/.leetcode/leetcode.toml`
[storage]
scripts = "scripts"

We write our python scripts:

# ~/.leetcode/scripts/plan1.py
import json;

def plan(sps, stags):
    ##
    # `print` in python is supported, 
    # if you want to know the data structures of these two args, 
    # just print them
    ##
    problems = json.loads(sps)
    tags = json.loads(stags)
	
    ret = []
    tm = {}
    for tag in tags:
        tm[tag["tag"]] = tag["refs"];

    for i in problems:
        if i["level"] == 1 and str(i["id"]) in tm["linked-list"]:
            ret.append(str(i["id"]))

    # return is `List[string]`
    return ret

Then we can run filter as what we write now:

leetcode list -p plan1

Well done, enjoy it!

计划是在这一个多月内达到 medium 不卡壳的难度，如果碰巧有小伙伴这阵子也在刷 leetcode，请联系小子，求搭伙儿！

[ZiLong]

点赞,顺便搭车看看有没有一起刷的....code 不易,期 leet code nan 上加难

[udtrokia]

在 Trello 上列了个比较平稳的计划 hhh

https://trello.com/b/hGBvNy0r

里面有微信群的二维码，一起刷的朋友点进来看看嘿嘿，Master LeetCode.

[hardwork]

我也在学 rust，学着玩

[metrue]

因为时间问题，现在改为每周周赛打卡.

[f1ren2es]

登录 leetcode 怎么做的呢，我记得之前 leetcode 登录用上了 recaptcha，然后就只能曲线救国用三方登录了。

[udtrokia]

@f1ren2es

recaptcha 确实搞不定...直接去掉了账号密码，读 chrome cookies 登录 = =

[udtrokia]

打一下卡.

+ 前天做了 10 道 easy 的 Linked-List
+ 昨天做了 21 道 easy 的 tree

Rust 刷 LeetCode 的感受是，我现在开始怀疑我以前写的都是假 Rust....好在越写越顺，昨天晚上的最后几道题都没有看讨论区的答案，包括之前面试 1 个小时做不出来的题，现在能够很轻松地写出来。

趁着讨论区的 Rust 解法还总是突破不了个位数 LOL，也 Post 上去一些小子自己的答案。

自学编程 3 年多，至今还是算法 0 基础(抱着我要是能够做出牛逼的项目，算法再渣也能混口饭吃的心态...) —— 打算这周奋发图强刷 300 道 easy，是不是怂货，够不够努力，自我验证下 🦀

[udtrokia]

更新一下哈哈

事实证明 300 道题的计划失败了，认怂！

刷完 easy 的链表和二叉树后，突然有灵感去做一个 wasm UI library，昨天刚刚阶段性完工，再一次开启刷题计划嘿嘿，但愿这次能够老老实实刷题直到找到工作吧！
