Retrieving data based on same character combination

Hi everyone,

I'd like to ask for help on the following problem. I have a set of 4 digit numbers stored in a list, and i was wondering if there is a way to retrieve certain numbers if it uses the same combination of digits within it?

For example, the number '0011' would be grouped with:

1001

0110

1100

0101

1010

etc.

Basically, the new list would retrieve every number which has two '1' digits & two '0' digits.

Any help would be greatly appreciated.

Cheers,

Alex

Hi Alex

I'm thinking of an addition of all characters, and then testing if the results are equal to 0, 1, 2, 3 or 4, for example.

In the file I enclose, I did that for 2, but it is easy to duplicate that for all the possibilities.

Is it what you want to achieve ?

Here's my approach,

Split the Characters up --> Sort them --> Then Join the results back together so that they match the Search Pattern and then do a cull Pattern on the original list.

Thanks for your suggestions Rhydro & Danny.

Rhydro, your method works for numbers that use two types of digits, but I start running into problems when i go on to using more types of digits (E.g. 0123 can be grouped with 0006).

Danny, I used your definition and it works perfectly!
