s1 = {1, 0, 1, 0, 0, 1, 0, 1}
s2 = {L, r, o, w, e, v, y, e}

s1 is a kind of a sieve i want to look through to s2, so i could pick
every letter in s2 wich correspond to every digit=1 in s1 so i could
obtain the word "love", this is like the trivial ciphers we know in
our childhood, i have the following approach, i hope there is other
versions.

p = Flatten[Position[s1, 1]]
out[]= {1, 3, 6, 8}

str = "";
Do[str = StringJoin[str, ToString[s2[[p[[i]]]]]], {i, 1, 4}]
str

Out[]= Love

thanks
