Hacktoberfest Part #5 (5nd PR of release 0.2)

Last PR of release 0.2! Pull Request #5 As I mentioned in previous blog post, this PR will also be in JavaScript algorithms repository. For the last PR I chose the math algorithms of finding the sum of n inverse numbers. One of the hard things in this repository is that there are no instructions given for algorithms to be developed. That is why I decided to implement the precision of result returned. Sum of n inverse numbers is a result that can be represented in the following way: n = 7 result = 1 + 1/2 + 1/3 + 1/4 + 1/5 + 1/6 + 1/7 Logic of my algorithm: The idea is that we get 2 numbers from the input -  n  and  precision If n equals to 0 then function returns 'undefined' Otherwise, function calculates the sum of first 'n' inverse numbers  The last step is setting up the precision and returning the result After that I wrote this code and tests for it. https://github.com/manrajgrover/algorithms-js/pull/61

Hacktoberfest Part #4 (4nd PR of release 0.2)

Fourth PR of release 0.2... Pull Request #4 For the next 2 pull requests I decided to stay in the same repository. For 4th PR I chose the string algorithm of finding the longest common substring. It was a little bit challenging to understand the logic of how to find it. Logic of my algorithm: The idea is we get 2 strings from the input, first and second If first bigger then second we swap them Then we need to iterate trough the second string, to find pieces of different sizes (from 1 to size of string) from first sting in the second string Once we find any piece from first string in the second string we return it The process continues until first string exists If string do not have any common substrings then program returns empty string After that I wrote this code and tests for it: And created the pull request: https://github.com/manrajgrover/algorithms-js/pull/60

LAB 1 - creating file using node.js fs module

LAB 1 #opensource Creating file using node.js fs module: If we want to work with file system in node, we will need to learn how to create files. In this blog post I will describe how to create and open files in node.js using the "fs" module. Here are the steps to do it: var fs = require('fs'); Include a module to your code. There are couple of methods to create a file: fs.writeFile("< fileName >",< content >,< callbackFunction> ); In this case a new file is created with the provided name.  After filling the file with content, callback function is called. If a file already exists , the file gets overwritten with a new file. fs.appendFile( "< fileName >",< content >,< callbackFunction> ); This function appends content to the file.  After filling the file with content, callback function is called. If the file does not exist, a new file is created with the name and content provided. Opening a file...
