Extrordinaly nice, but whay does it do extra checks - crop some results ?
i simply added a counter($inC=0), in the beginning and told it to ++ before --$cand;, and at the end it printed 14 instead of 10, and only ehen i put the $inC++ before the print in the while() it printed 10.
i'm sorry to repeat that i work with hundreds of 1's and 0's, and every false checking costs.

All of your code are wonderful, but unfortunatly i like the second code i posted the most, it only needs to get fixed in the part where it gets the $Oc and $Zc; i would have replaces this while() to a foreach() of an array that contains all the distances between ones and zeroes sets(e.g, in the string 0010111 the distance's array should look like qw(2 1 1 3)), but for that i need to know all the distances variaties( without repetition) from @distances= ($ones, $zeroes) upto @distances= ($zeroes, $ones) when the @distances reach the array of $ones+$zeroes-1 times 1 ( if $ones=2 and $zeroes=3, when @distances=(1,1,1,1,1)) the rest of the @distances are the reverse of the previose sets in reverse:
11000 [2 3] 10100 [1 1 1 2] 10010 [1 2 1 1] 10001 [1 3 1] 10011 [1 2 2] 01010 [0 1 1 1 1] 01001 [0 1 2 1] 00110 [0 2 2 1] 00101 [0 2 1 1 1] 00011 [0 3 2]
