Leetcode-go is a CLI written in golang for retrieval and submission of problems hosted on https://leetcode.com/. You can search problems, download them, run them against sample/your own testcases and submit them to your leetcode profile.

If you have golang installed, you can install the app using go install. Simply write this to in your terminal.

go install github.com/Manan-Prakash-Singh/leetcode-go@latest

There is no need to insert your username and password. Just make sure you are logged in into your accout in your browser. It searches through your browser cookies and finds the csrftoken and LEETCODE_SESSION token. For now, this works for firefox and chrome on Linux. To test if you are authenticated, type

leetcode-go auth

Note : I still need to test it on MacOS and Windows.

To download the problem, you can use leetcode-go problem "problem name in quotes" --lang cpp. This will download if it can find the problem in cpp. But this requires you to know the full name of thee problem, which can be cumbersome, therfore, you can use leetcode-go search "search term" instead to search for the problem and then it will automatically ask you to language that you need to download the problem in. The problem statement is downloaded in a problem.txt file whereas the code snippet is downloaded as your chosen language.

When you download the code using leetcode-go, it saves it in the form "longest-increasing-subsequence_300". This format is expected when the filename is parsed, so don't change this. Moreover, the sample test cases are written inside the program file, enclosed inside block comments /* */. Each test case is seperated by ;. You can add your own test cases in it but make sure to keep the block comment at the top of the file.

/*

[2,7,11,15]
9;

[3,2,4]
6;

[3,3]
6;

*/
class Solution {
public:
    vector<int> twoSum(vector<int>& nums, int target) {
        
    }
};
