Add a page to topics on Hashtables with resources and problem sets. If you have been studying for interviews and have some favorite problems and resources at hand, please help us out!

Add resources and problem sets to ./topics/backtracking.md

This issue is reserved for the WWCode Hacktoberfest Demo!

Our next set of Zoom presentations and practice sessions (through the end of 2020) are on Arrays and Hashmaps. We are 
looking for help curating good resources and problems for these event. If you are currently interviewing or have recently 
finished a stage of interview prep, please consider sharing your favorite videos, articles, and problems on Arrays and 
Hashmaps! Here is the current state of our Arrays page. We don't have a Hashmaps page, if you would like to start it up, 
please consider taking on this issue.

Update our trees-graphs topic page: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/trees-graphs.md

With links to specific trees and graphs chapters in this online text:
http://jeffe.cs.illinois.edu/teaching/algorithms/

Add resources and problem sets to dynamic-programming.md

Edit our topic page on arrays-strings, which lives here: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/arrays-strings.md

• Select 3 Easy, 3 Medium, and 3 Hard problems

• Put them in a table format, see https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/linked-lists.md for an example

• Please include these two problems in the Medium section:

• https://leetcode.com/problems/merge-intervals/

• https://leetcode.com/problems/interval-list-intersections/

Instead of providing links to leetcode lists, copy each problem from the lists into the /md file into tables. Provide separate tables for each difficulty level. Each problem gets a row. Provide link to problem description, solution, and link to a community generated example. Here is a template:

Easy problems

Medium problems

Hard problems

Add at least easy and medium problems with endorsed solutions to ./topics/recursion.md

We are keeping an eye on github's efforts to create tools for renaming the default branch. Rather than move right now, I'm ok to wait until December for tools github develops to make the move. However, this is a small repo and if you would like to take on the task of an early renaming, please feel free to take this issue!

Add a stacks and queues topic page to ./topics/stacks_queues.md

Resources for this issue:

• The template for a topic page: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/template.md
• Problem sets to select problems for the topic page: https://github.com/WomenWhoCode/wwcsf-algos#2e-problem-sets
• Leetcode curated Top Interview Questions:
  • Easy: https://leetcode.com/explore/interview/card/top-interview-questions-easy/
  • Medium: https://leetcode.com/explore/interview/card/top-interview-questions-medium/
  • Hard: https://leetcode.com/explore/interview/card/top-interview-questions-hard/

Please make sure you have done the following before requesting a review:

• In the problem set tables, make sure that the code examples link points to the correct folder in https://github.com/WomenWhoCode/wwcsf-algos/tree/master/code-examples/
• Please make sure that all leetcode problems you select are accessible without a leetcode account. If the solution is not accessible, you can still use the problem, just link the solution to the solution discussion.
• Please add a link to your new topic page to the repo's README in this section: https://github.com/WomenWhoCode/wwcsf-algos#3-resources-and-problem-sets-by-category

The code takes each digit of the numbers to be added in separate nodes of the linkedlists. Carry generation handling is also looked after. Please assign me this issue.

Add resources and problem sets to ./topics/sorting-searching.md

This is issue is reserved for our Hacktoberfest demo.

We only have 2 Easy problems on our Sorting and Searching page. Please add this one to the Problems/Easy table in the file topics/sorting-searching.md

https://leetcode.com/problems/two-sum/

Please note that the recommended Solution is locked behind a paywall. Instead, provide a link to the solution discussion:
https://leetcode.com/problems/two-sum/discuss/?currentPage=1&orderBy=hot&query=

Please edit the Problem Sets section on this markdown file: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/trees-graphs.md

• Please delete the "Google kickstart" problems

• Please add problems to the Easy, Medium, and Hard sections, so that there are three problems per section.

• If a problem is in the wrong section (for example a Medium problem in the Easy section), please move it to the appropriate section.

Guidelines:

• Check out these lists for potential problems to add : https://github.com/WomenWhoCode/wwcsf-algos#2e-problem-sets

• Please provide a link to the official Leetcode problem page, instead of to the card or article. The page we want has a simple url of the form leetcode.com/problems/[problem-name]. Here is an example of the correct leetcode page. You will have to search leetcode for the problem title to find the correct page with a URL that starts with leetcode.com/problems.

• Only post problems that are available through a free leetcode account.

Add resources and problem sets to ./topics/design.md

Please edit the Problem Sets section on this markdown file: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/trees-graphs.md

• Make 2 different sections for Tree problems and Graph problems.
• Organize problems by difficulty into tables. Here is an example from Linked Lists: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/linked-lists.md#problem-sets

Add tables for Tree problems:

• Easy Tree Problems: pick at least 3 Easy ones (some of these are not labeled easy)
• Medium Tree Problems: Binary Tree Inorder Traversal, Populating Next Right Pointers in Each Node, Construct Binary Tree from Preorder and Inorder Traversal
• Hard Tree Problems, Word Ladder, Lowest Common Ancestor of a Binary Tree, Binary Tree Maximum Path Sum
• Please provide a link to the official Leetcode problem page, instead of to the card or article. For example, don't link to this page, link to this one. You will have to search leetcode for the problem title to find the correct page with a URL that starts with leetcode.com/problems.
• Only post problems that are available through a free leetcode account.

Create a markdown template in /topics that can be used as a template for further topic pages. You can base the template off of https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/linked-lists.md

Add resources and problem sets to ./topics/big-O.md

Please edit the Problem Sets section on this markdown file: https://github.com/WomenWhoCode/wwcsf-algos/blob/master/topics/trees-graphs.md

• Please delete the "Google kickstart" problems

• Please add problems to the Easy, Medium, and Hard sections, so that there are three problems per section.

• If a problem is in the wrong section (for example a Medium problem in the Easy section), please move it to the appropriate section.
