Example

For example, given this config (can be found in ~/.leetcode/leetcode.toml):

[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
# struct Solution;
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-cli can work on OSX and Linux. If you are on a different platform, there are problems with caching the cookies, you can manually input your LeetCode Cookies to the configuration file.

[cookies]
csrf = "..."
session = "..."

For Example, using Chrome (after logging in to LeetCode):

Step 1

Open Chrome and navigate to the link below:

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

Step 2

Copy Content from LEETCODE_SESSION and csrftoken to session and csrf in your configuration file, respectively:

[cookies]
csrf = "${csrftoken}"
session = "${LEETCODE_SESSION}"

Programmable

If you want to filter LeetCode questions using custom Python scripts, add the following to your the configuration file:

[storage]
scripts = "scripts"

Then write the script:

# ~/.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 run list with the filter that you just wrote:

leetcode list -p plan1

And that's it! Enjoy!
