Algorithms and Data Structures with ES6

This repo contains basic algorithms and data structures implemented with ES6.

It provides the following features:

• Basic Algorithms with Data Structures
• Sorting: quicksort, mergesort, heapsort
• Dynamic Programming: factorial, max sub array
• Misc
  • String interview questions (reverse, palindrome)
  • Decimal-to-Roman-Numeral conversion
  • Chess knight shortest path
• Code written in ES6
• Babel transpiling through a simple gulp task
• Linting with eslint using the AirBnB rules
• Unit tests with mocha
• Test coverage metrics with instanbul
• Latest modules used for all dependencies, including babel v6
• JSDoc style comments used to document the code

Usage

import { QuickSort } from 'algs4j';

const arr = [10, 9, 8, 7, 6, 5, 4, 3, 2, 1];
console.log(`Unsorted Arr: ${arr}`);
QuickSort.sort(arr);
console.log(`Sorted Arr: ${arr}`);
// arr is now [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
