[=?Utf-8?B?RGlvZ28gQWx2ZXM=?=]

Greetings,

I am trying to sort this values on a datatable

1
2
12rw
3
12r
4v
10a
e1
1w3

This was suposed to be sorted like this

1
1w3
2
3
4v
10a
12r
12rw
e1

I can't find a solution to sort this way.

Can anyone help me?

You could parse each string to get the preceding numeric values until the
first character is found. Use the numeric values converted to a number to
sort. When the numbers match, use the characters that follow to make the
decision. Similarly, if the string starts with a character use that to sort.
You might want to write a method that does the comparison between two strings
the way you want and use that in a bubble sort function.

Why would you use a bubble sort function for this, or any application,
for that matter? It takes O(N^2) time to do this, just way too long. There
are much faster sorting algorithms out there (quicksort, for example).

I don't know, it's the first thing that came to mind :) Obviously you can do
it in many other ways as long as you understand where to start.
