Merge lines using XOR operations bits

Hi

I need to do an algorithm that read a textfile have 14 Characters (Numbers 1 to 7)

Example:

44444444444444
44444444444442
14444444444444
42444444444444
..ETC

I must read each line and find lines with difference 1 or 2 characeters, in example above the first line and second line have difference
one character I must to do a XOR in each position

doing in first and second line

Each line can use only 1 time
The lines used can not to use again , then first and second line can not to used

44444444444446

But each row will can in maxime two symbols differents of the (1, 2 and 4)

44444444444446 have only one symbol ( 6) , then I must to read others line to find more row with one difference

Doing XOR between 44444444444446 and 14444444444444

See that the number 6 in bit format is
110 ==> 6
and the number 4 in bit format is
100 ==> 4

Then 6 contain 4 then will can to do XOR in each column

544444444444446 , Now This line have two symbols differente of the (1,2 and 4 ) , 5 and 6 then It do not need in others rows,

but the rows used
44444444444444
44444444444442
14444444444444

Can not to used again , Someboy can to help me to do a algortihm to read each row and to do operations with bits
what best language ?

I know a little VB and learning Python

I don't quite understand what you are asking but you seem to know what you want to do and how to do it using XOR.

It looks like Python is supporting bitwise operations and since you're learning that language why not use it? Then if you have more specific questions regarding implementation you can ask at a Python forum.
