competitivecode's Issues

CodeSignal Advance DP problems

Solutions to advance DP problems like K-Palindrome, paintHouses, maximal square in C++

Solution needed

A simple solution is needed for this problem: 3D surface Area

Solve Sparse Matrix Problem

Any solutions or logic to solving the Sparse Matrix Multiplication problem is welcome.

When submitting a solution, Please include comments in your code to explain the logic used. More emphasis is given to the technique used in solving rather than the code itself.

Added codechef practice problems inside codechef solutions

Pls check my solutions from previous codechef long challenges in codechef random practice problems...Please accept my PR.(Hacktoberfest)

Add the 'Hacktoberfest' topic to this repository.

Hello,

Hacktoberfest 2021 is already started and to make this repository visible to people who want to contribute to open-source projects, I request you to Add the Hacktoberfest topic to your repository so that folks know you're participating in Hacktoberfest.

Drawing book folder not shown in the forked version

Add Codeforces problems and solutions

It would be great if we can have some more interesting problems and their solutions from Codeforces ✨

Preferred difficulty level: Easy/Medium/hard (please refrain from adding too beginner/trivial questions)
Refer Contribting.md and read all points carefully before sending a Pull request.

Keep this in mind: When adding solutions, ensure that you provide sufficient comments so as to explain the logic used. More emphasis is given on understanding the technique used rather than the code itself 😃

Happy Contributing 😄

Solution needed

A simple solution with a brief explanation of the logic for this problem: Drawing book

This repo is not valid for Hacktoberfest

Hacktoberfest recently announced in their discord channel that repositories focused on DSA would be excluded.

Solution needed

A simple solution with brief explanation is needed for this problem Sequence Equation

Anyone can work on this and send a PR. (multiple solutions in different languages are welcome)

If one solution has already been added, You may also add your solution (provided it is not exact copy).
Number the solutions accordingly (eg: solution2)

Add Useful Resources for Competitive Coding

A new file USEFUL_RESOURCES.md has been created for adding some useful resources that can help with Competitive Programming. ✨
Some examples include Articles related to CP/DS & Algo, tips for cracking ACM ICPC/Code Jam etc, Cheatsheets, tips for cracking coding interviews and many more.
If you have got any such links to some resources which you feel would be really useful, you may add them to USEFUL_RESOURCES.md 😃

Alternatively, If you have got something useful but is not a link which can be added (For eg: some code snippet etc), You can create an Issue for adding the same to this repository. 🙃

Improve Documentation

The readme and contributing documentations can be improved

• Adding emojis
• Correcting grammatical/spelling errors

Addition of Hackerrank Problem and its solution

Hey, Can I add a hackerrank solution to this Repository? , If yes, then can you assign me? :-)

All binary search problems from Interviewbit

Code and explanation for all binary search problems at Interviewbit in C++.

Delete duplicate folder and merge contents

There are currently 2 folders for CSES Problems. Copy the contents of cses_problems into CSES_problems and delete the cses_problems folder.
I am not able to do this since both folders automatically merge when cloning on Windows machine.
So if anyone with Linux OS will be able to do this, then please reply here.

Note: Since this involves deletion and modification of files/folders, it would be better if only those having prior experience with Git and Github take up this issue. So please reply here if you would like to take up this issue.

Add interesting problems and solutions from Spoj

It would be nice if interesting questions and their solutions can be added from Spoj ✨
Create a folder named Spoj_problems and add.

Preferred difficulty level: Easy-Medium/hard (please refrain from adding too beginner/trivial questions)
Refer Contribting.md and read all points carefully before sending a Pull request.

Keep this in mind: When adding solutions, ensure that you provide sufficient comments so as to explain the logic used. More emphasis is given on understanding the technique used rather than the code itself 😃

Delete Duplicate folder

There are currently 2 folders for CodeChef Problems. Copy the contents of CodeChef_Problems into CodeChef_problems and delete the CodeChef_Problems folder.
I am not able to do this since both folders automatically merge when cloning on Windows machine.
So if anyone with Mac or Linux OS are able to do this, then please do and send a PR.

Note: Since this involves deletion and modification of files/folders, it would be better if only those having prior experience with Git and Github take up this issue. So please reply here if you would like to take up this issue.

New Interesting problems can be added into misc folder

The "misc" folder looks kinda empty . It would be nice if we can have more potential Interesting problems from CP 😃

Any problem that you add must satisfy the following

• The problem must be related to the Competitive programming domain
• The problem must be your own. You may add your name as Author and add any personal links if you wish to.
• You can name the problem anything you like. Also give the same name to the folder.
• The problem.md file must have the following
  • Problem statement which is clear and easy to understand
  • Input format, Output format
  • Constraints (if any)
  • Sample testcases with detailed explanation to at least 1 or 2 depending on the difficulty level
• You may also add additional testcases in a separate file called testcases.txt
• Adding a solution is optional. Please refer Contributing.md if you are planning to add a solution as well

If you have got some of your own interesting questions which satisfy all the above, then feel free to send a PR and reference this issue 😀 ✨

(Note: The idea is to collect some potentially challenging questions. Hence please avoid trivial questions like swap 2 numbers, finding factorial/fibonacci, largest of 3 numbers etc 😅).

Add your solutions

You can add your solutions to any of the existing questions.
Refer Contributing.md

Add CodeChef problems and solutions

It would be great if we can have some interesting problems and their solutions from CodeChef

Refer Contribting.md and feel free to add some problems from CodeChef and its solutions.

Keep this in mind: When adding solutions, ensure that you provide sufficient comments so as to explain the logic used. More emphasis is given on understanding the technique used rather than the code itself :)

UPDATE: Since there is a great response, it would be better if the problems added are restricted to easy/medium/hard levels.
Please refrain from adding too beginner/Trivial problems
