[Priyank Shah]

Hi,

One method, and I stress this is only one method, is the Levenshtein distance at

http://en.wikibooks.org/wiki/Algorithm_implementation/Strings/Levenshtein_distance#Ruby

and it has code, in ruby!

"Difference" in this case does not seem very well defined.

Hi,

I have two strings, like
@a =3D "hello"
@b =3D "h123llo"

so in that how can i print diffrence?

i want difference like user know which diffrence on which character.

There is strmask (http://rubyworks.github.com/strmask/)

Also the Levenshtein distance is String#edit_distance in Ruby Facets.

There's a "differ" gem which could be useful for you.

Thanks to you all but i want difference so i used

http://codeidol.com/other/rubyckbk/Files-and-Directories/Comparing-Two-Files/

And its working fine but i actully want exact difference.

and it just shows me number of differences.

So if you have any idea regarding this then please suggest.

As in:

@b.split(//) - @a.split(//)
