Can I work on coding the Algorithms to solve the following problems
Given n activities with their start and finish times, Select the maximum number of activities that can be performed by a single person, assuming that a person can only work on a single activity at a time.
I am adding the dijkstra wiki under README.md file.
Please provide a short, clear description of the problem
need to add searching algorithms for graphs
If you know how to solve the above, please provide details here.
I want to add the algorithms for graphs in java
For those comfortable with GitHub , it should not be much of a problem.
Please provide a short, clear description of the problem
Please list the steps to reproduce the above problem
What did you expect to happen
What actually happened
If you know how to solve the above, please provide details here.
Pre-order :-
visit the root node
traverse the left sub-tree
traverse the right sub-tree
In-order :-
traverse the left sub-tree
visit the root node
traverse the left sub-tree
Post-order :-
traverse the left sub-tree
traverse the right sub-tree
visit the root node
all nodes of tree should be traversed.
I would like to add basic tree operations like dfs,bfc,lca,etc
could you assign this topic to me?
There are some study materials and READMEs here and there all over the repository. Since this repo was meant for people to get a compiled list of algorithms, I think it would be better to just create a site and post all the study materials there. That would make it more readable and easily accessible.
I have created a jekyll blog, that can be accessed using codeiiest.github.io/Algorithms. Check the gh-pages branch for contributing.
2 new folders linkedlist and Linked-list created
Remove the extra ## heading formats in the readme under HeapSort folder.
since @AdvikEshan you worked on this, I am assigning to you
I would like to document prims ,kruskal,Dijkstra's algorithms
Will be coding in Java,C and describing pseudocode for algo
To solve the following problems:
So the current code base contains all the algorithms and ds codes in a hapazard way
We intend to have a more organised structure
So the major directories will include some thing like this
Please do not submit any new PR to the master now. Once the file gets structured, you are free to submit.
adding stack program in cpp . stack is abstract data type with two principle operations push and pop.
Please list the steps to reproduce the above problem
push,pop,peek operations will tested with an array and push will add elements ,pop will destroy the topmost element peek will be used to view topmost element
same as expected.
upload the code for the operations.
i am assigning it to myself and adding the program in cpp
I want to add binary search algo in python language
will add Readme.md file also.
I want to add Cycle detection algorithm for a Undirected graph
--

--
upload the cycle detection algorithm for undirected graph
To implement DFS in a graph
Implementing the Algorithm as I had Learnt from CLRS earlier this month via C or C++
DFS traversal of graph is obtained
To be tested and coded.
Bellman-Ford algorithm for shortest distance, and also for negative cycle detection.

Remove a.out file from Algorithms/Competitive Coding/Dynamic Programming/Edit Distance/
In the linked list folder there is no algorithm to detect loops in it. I would like to contribute to that module.
Double linked lists are another set of important data structures and algorithms.
Include algorithms for performing operations pertaining to doubly linked lists.
A repository rich with double linked list algorithms.
Expected Outcome
If you know how to solve the above, please provide details here.
Documentation is an important part in open source. Therefore it is necessary to write it.
Write Readme.md files for each program in the repo.
Randomized version of quicksort is mostly implemented in real life and is missing in the repo as it is the randomized quicksort which gives it the worst case O(nlogn) complexity and not the naive implementation.
Code of randomized quicksort will be added.
I will like to add the randomized quicksort in the quicksort folder.
i am going to implement a few math based algorithms like Lucky number, Babylonian method for square root..more and more.
##STEPS TO REPRODUCE
Will be coding the algorithms in C++.
what will happen i will describe with example.
I'd like this issue to be assigned to me so that I can implement the following.
Can I add some DP algorithms coded in C or C++?
I would like to add
Segment trees:
Segment trees are very useful for range queries. Segment trees do the update and query operation in log(n) time. They are binary trees in which the given array is modified into a tree which help in solving the query.
In the graphs folder I would like to contribute towards topological sort.
There is no format for PRs and how to contribute. There should be a contributing.md
WIll we implementing a few math based algorithms like:
(1) Factorial
(2) Fibonacci Series
(3) Project Euler problem-1
(4) An algorithm for a Random Number Generator
Will be coding the following algorithms in C,C++ or Python.
I'd like this issue to be assigned to me so that I can implement the following.
I want to add some popular maths algorithms to this project in C++.

Instead of searching all the through the list, how about creating folders like Bit manipulation, dynamic programming , greedy algorithms and so on. This would create a neat and tidy repo
(Not a defect) I would like to implement some popular mathematical algorithms in Python 3.x
@prateekiiest I would be grateful if you allow me to contribute the above to this repo.
Need to add algorithms for finding the minimum spanning tree

add algorithms for finding the minimum spanning tree
I am adding the solution for RSA ALgo. I have created a folder "Cryptography_Algorithms" under which i am adding the solution.
The README must be made more attractive and have more info.
Because
A good readme => A good project
There is a file containing all the operations that can be performed on a linked list in Algorithms/Competitive Coding/Linked List but it's only pointer based.
I would like to add an array based 'Linked_list_operation' file using C++ and if allowed I would like to rename the current one to 'Linked_list_operation_based_on_pointers'
The repository will now have both array based and pointer based Linked List operations files.

I would like to add an array based 'Linked_list_operation' file using C++ and if allowed I would like to rename the current one to 'Linked_list_operation_based_on_pointers'
I want to propose new commits which include files containing a number of important algorithms in C or C++ .
New commits can be added with the required algorithms.
A rich repository with a number of useful algorithms for student purpose like linked lists, stacks,queues,circular queues ,searching and sorting techniques etc.
What did you expect to happen
The proposed outcome
If you know how to solve the above, please provide details here.
I want to work on a cpp file which contains code for circular queue
A cpp file will be added with the required code
A file for circular queue
Same as expected
The current readme contains only search and sort algo description.
Transfer into corresponding directories.
Like Competitive_Programming/Sorting/Sorting_Readme.md
Competitive_Programming/Searching/Searching_Readme.md
Knuth morris pratt algorithm is a string matching algorithm which matches the pattern in the text and indicates the location of occurrence.
If we provide pattern and text strings to the program then it gives the location of occurrence in the text.
This issue cover following algorithms:
1.Gradient descent
2.Normalize equation
for different model such as linear regression, polynomial regression and logistic regression.
I wish to PR more Backtrack problems:
I think it would be better if we create a separate folder for sorting algorithms in python as there might be people who only know Python and might know C or C++
As a result it might become difficult for them to comprehend the sorting algos in C and C++
Therefore I'd like to assign this task of creating a separate folder with Sorting algos in Python and write a couple of sorting algos into it too!
I wanna upload some resources here, for everyone to know the basics. I came across these resources in another repo and I feel it will help everyone more.
I will be uploading the codes for these alongside as well
Union-find algorithm is used in detecting cycles in graph. I would like to document this algorithm in c++. This is also know as disjoint set method
Would like to work on bitwise operations and programs related to it.
