I have been looking around the web for a while and I am wondering if there is a 'stable' defacto implementation of quicksort that is generally used? I can write my own but why reinvent the wheel......
I have an array of nested objects: [ {_id:1, parent:0, name:'Z'}, {_id:4, parent:0, name:'A'}, {_id:2, parent:1, name:'H'}, {_id:8, parent:2, name:'G'}, {_id:5, parent:4, name:'M...I implemented quicksort and found that it work faster than native .sort() method, here is the Performance test Why and how is this happening?...
I'm working with QuickSort and I tested these 2 algorithms on LeetCode for this problem. Both algorithms work, but one seems to be significantly faster than the other one and I don't understand why. This one exceeds time limit of LeetCode:...
I have the following: function quickSort(array, low, high) { var len = array.length, l = low || 0, r = high || len - 1, m = Math.round((l + r) / 2), t; do { while (array[l] < array[m]) {...I've never coded this myself before, unfortunately. My implementation operates on a custom class based on sorting the "date" field. Yes I am fully aware I can use the built-in Javascript sort and specify the comparator function but that&#...
This question already has answers here:...
My Quicksort is working perfectly and the code is here: https://gist.github.com/RoloRobot/b2e15af9ab0d8c1bdbdd What I want to do is make it sort not only numbers, but strings and objects as well. How would I go about doing that? Any help would be a...
I'm currently digging into the theoretical field of algorithms for university and I've implemented a version of the Quicksort based on how I understood the algorithm works. After that I've compared it to existing solutions and my implemen...
I tried to implement QuickSort algorithm from Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, Clifford Stein - Introduction to Algorithms, Third Edition - 2009 * Section 7.1 in JavaScript. So here is my implementation: function swap(ar...
