Yes, exactly. You have put very nicely in words.

I have few more ways in mind. Based on the guess, it can generate set of numbers that matches the conditions. Example: (1122:2:1) can give the set: x112,1x12,12x2,122x. Later on I can combine the sets( cross product) to see, which combination works good ( instead of generating a possibly complex regexp)

(1122:2:1) can give the set: x112,1x12,12x2,122x There you have me totally confused. Take the second element from your set, `1x12`. The two digits in their correct positions must be the first and last, no? So that means that the `1` in third position must exist in the target string, but at a different position than in the "guess" string. Do you see the problem yet?	[reply] [d/l] [select]
