Now lets say you need to sort this in the ascending order using bubble sort. So, you iterate the array and swap adjacent elements which are ordered otherwise. Here is what you will get after the completion of the iteration [4, 3, 2, 1, 5] Now if you do this another time, you will get this: [3, 2, 1, 4, 5]
I believe that in a bubble sort, once the i loop has completed an iteration, then the i'th element is now in its correct position. That means that you should write the j loop as. for (var j = i + 1; j < records.length; j++) Otherwise your bubble sort will be (even more) inefficient.
Arrays can be sorted with with sort method - so let's just use that: return num.toString().split('').sort().join(''); numSort converts the argument to a string, splits it into an array, sorts it numerically and then joins it up again. If you wanted a number to be returned (instead of a string) just use parseInt.
Mmm, I skimmed the question and didn’t notice you weren’t actually doing bubble sort. There would typically be a sorted flag that gets reset at the beginning of the loop and set if a swap is performed, for a Θ(n) best case instead of Θ(n²).
Recently stumbled upon a problem. Basically, the program needs to sort an array of objects by one of their fields without actually using the sort function. I've tried this code using bubble sort algorithm, but it doesn't seem to be working:
So the setTimeout(function, milliseconds) function in JavaScript takes as a first Parameter a function which then will be executed every 'milliseconds' milliseconds. In the function you will have to implement an algorithm, that solves one step of Bubble Sort to the array that it gets as a parameter. The next time the function gets called, you ...

Jan 31, 2021 at 11:24. You have an apparently okay bubble-sort implementation in your code, that can be used for sorting any array of numbers. What you don't have is an array of numbers, as you have text in a textbox. Use string.split() and parseInt() (in a loop or array.map()) to get an array of numbers from the input or your own generated string.
1. If you want to place a new value at a position in an array, the old value at that position will be overwritten. const arr = [0, 1, 3, 2] We'll use this array as an example. If I want to swap the values at arr[2] and arr[3], I could start by setting arr[2] = arr[3] resulting in the following.
4. Have a bubblesort routine similar to this. I need to make it more efficient by stopping the loop when the array is sorted or if the array is already sorted. function sortNumbers(listbox) {. var x, y, holder; // The Bubble Sort method. for(x = 0; x < ranarray.length; x++) {. for(y = 0; y < (ranarray.length-1); y++) {.
