// Category: algorithms

// Percent: 32.90331%
// Given an integer array nums, return all the triplets [nums[i], nums[j], nums[k]] such that i != j, i != k, and j != k, and nums[i] + nums[j] + nums[k] == 0.
//
// Notice that the solution set must not contain duplicate triplets.
//
//
// Example 1:
//
// Input: nums = [-1,0,1,2,-1,-4]
// Output: [[-1,-1,2],[-1,0,1]]
// Explanation:
// nums[0] + nums[1] + nums[2] = (-1) + 0 + 1 = 0.
// nums[1] + nums[2] + nums[4] = 0 + 1 + (-1) = 0.
// nums[0] + nums[3] + nums[4] = (-1) + 2 + (-1) = 0.
// The distinct triplets are [-1,0,1] and [-1,-1,2].
// Notice that the order of the output and the order of the triplets does not matter.
//
//
// Example 2:
//
// Input: nums = [0,1,1]
// Output: []
// Explanation: The only possible triplet does not sum up to 0.
//
//
// Example 3:
//
// Input: nums = [0,0,0]
// Output: [[0,0,0]]
// Explanation: The only possible triplet sums up to 0.
//
//
//
// Constraints:
//
//
// 3 <= nums.length <= 3000
// -10⁵ <= nums[i] <= 10⁵
//

// end_markerSome linting tools/lsps will throw errors unless the necessary libraries are imported. leetcode-cli can generate this boilerplate automatically if the inject_before key is set. Similarly, if you want to test out your code locally, you can automate that with inject_after. For c++ this might look something like:
[code]
inject_before = ["#include<bits/stdc++.h>", "using namespace std;"]
inject_after = ["int main() {\n Solution solution;\n\n}"]leetcode pick 1leetcode pick --name "Two Sum"[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].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![];
}

Your input: [2,7,11,15], 9
Output: [0,1]
Expected: [0,1]
leetcode exec 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.
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 Firefox (after logging in to LeetCode):
Open Firefox, press F12, and click Storage tab.
Expand Cookies tab on the left and select https://leetcode.com.
Copy Value from LEETCODE_SESSION and csrftoken to session and csrf in your configuration file, respectively:
[cookies]
csrf = "${csrftoken}"
session = "${LEETCODE_SESSION}"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 retThen run list with the filter that you just wrote:
leetcode list -p plan1That's it! Enjoy!
