Regular expression

Question

$(\ 0\ +\ (\ 1\ (\ 0\ 1^*\ 0\ )^*\ 1\ ))^*$

How can the above regular expression produce this string:

$1100100011011001011$

Comments

the above RE is equivalent to,

(0 + 1(00 + 010 + 0110 +....)*1 )*

writing 1100100011011001011 in partition as 11 00 10001101 1001 0 11

now, carefully see each partition can be derived from above RE

Understood, Thanks.

In the 2nd partition from left, i.e 00, it should be 0 0 instead of 00 .right?

yes, it is trivial so i wrote it as 00 only.
