Code should go inside data_structures/cpp (yeah, we don't have this folder yet, please create :) )
Any contribution is welcome!

Hello @larissalages , I wish to add new functions to the code. I can extend it by implementing more traversals & checks for binary tree . Could you please assign it to me & label/merge my pr for issue #13

project euler problem solutions in C++ under new folder at the root of the repo.

The code should go inside data_structures

There are some algorithms without unit test cases

We have an implementation of Merge Sort in C++ in https://github.com/larissalages/code_problems/blob/master/classical_algorithms/c%2B%2B/mergesort.cpp
but we don't have unit tests for it

Not all leet problems that are in the repo are in the readme, please add then and include in the specific section (python/c++/java)

Hi @larissalages I would like to add solutions for the 30 days of code challenge in HackerRank. I am good in Java programming language. Please assign this task to me. Thank you.

Hey, how are you?
I just made a PR for leetcode problem 38. Count and Say in python (:

We only have quicksort in Python, please implement in C++.
The code should be inside the folder "classical_algorithms"

On readme we have tables with the link of the problem and the link of the solution on our repo, but is not up to date. Please update readme, any contribution, even small, is welcome.

Code should go inside the folder classical_algorithms

Some algorithms are missing unit tests, you can see the list on the readme. Tests should be created inside a folder tests inside the respective folder language.
Any contribution is welcome! :)

@larissalages can you assign me to the task of adding segment tree data structure, it's explanation and some of it's code like -

• Range sum
• Maximum element in a range with it's frequency
• Inversion count using segment tree
• Binary search on tree to find the element greater than K elements
• Range update (Lazy propagation)

I would even like to create a README.md file explaining a bit about segment trees.

We have the code for Merge Sort and Quick Sort in java but we don't have unit tests for them, please create a separated file for test the class of one of these algorithms.

When there is negative numbers the sorting is not right.

Code should go inside the folder classical_algorithms

I would Like to add Basic Python Dictionary, How it works on python folder in your repo. :)

Hello, you need help?
i volunteer me for answer the issues or for verify the pull request(remembing that the final word is you)

The code should go inside classical_algorithms

We have two folder for Hackerrank in the repo, Hackerrank and hackerrank, move the files from one folder to another and remove the extra folder.

We have the code for Merge Sort and Quick Sort in java but we don't have unit tests for them, please create a separated file for test the class of one of these algorithms.

data_structures now has a folder called C++ and another called Cpp, they should be merged because it is the same language. Move the files from one folder to another and delete the old folder.

A lot of links main in README.md present in main directory of this repo, don't open, they result in error 404.

In this problem when i used a[i][j]=1+a[i-1][j-1] use because when we consider i the element or j th element than that is taken in LCS but my solution on passed all solution in atcoder dp contest link is provided below

@larissalages I can add a solution to the leetcode problem 151- Reverse Words in a String (Medium).
please assign me this issue.

I'm on to it!

I was browsing through the issues finding something to contribute to and found out that a lot of issues already have merged pull requests. But the issues are not closed. This could make it difficult for newcomers to contribute.
