can anyone give me a example of a radix sort

Hello,
I have done the Radix with queue
here you are an example
But the queue is my own Queue

retrieve: return the first element
serve : delete the first element;
dequeue: insertlast

``````#include <iostream>
using std::cin;
using std::cout;
using std::endl;
#include <cstdlib>
#include <ctime>
#include "queue.h"
#define …``````

can anyone give me a example of a radix sort

Here's an explanation to complement Abu's code example:

A radix sort works with the digits of a number, working from the least significant digit to the most. Here's a sample set of numbers:
423 586 403 171 92 536 …

If you want here you are my own queue class

This program is generates 100 random integers and store them in the latest Queue then start sorting

Here's an explanation to complement Abu's code example:

A radix sort works with the digits of a number, working from the least significant digit to the most. Here's a sample set of numbers:
423 586 403 171 92 536 234 243

First, sort the numbers by the least siginificant digit (ones). For this algorithm to work, your buckets have to be order-preserving.
171 92 423 403 243 234 586 536

Then, sort them by the next most significant digit (tens):
403 423 234 536 243 171 586 92

Now hundreds:
92 171 234 243 403 423 536 586

...and they're sorted. Each step doesn't have to be a bucket sort; any order-preserving sort will work.

Can anyone provide me the Radix sorting through other than the Queue.w8ng for the replyyyyyy......

You can use buckets to code radix sort.
