Modifying a query string without reloading the page
...aid. Here it is an example that might help you to implement it properly. I tested and it worked fine:
if (history.pushState) {
var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?myNewUrlQuery=1';

I've tested the algorithms myself and I've seen that Quicksort has something special indeed. It runs fast, much faster than Heap and Merge algorithms.
