given regular expressions are along with there meaning
I. 0(0+1)* all strings starting wiith 0
II. 0* 10*1(0 +1)* all strings containing atleast two 1's
III (0+10)*(1+€) all strings containing no consecutive 1's
IV.[(0*10* 10*)* +0*]10* now i don't know exactly what this is representing ,but it does not necessarily start with 1
Reversed expressions can be writtten as below
1.(0+1)*0 all strings ending wiith 0
2.(0 +1)*10*10* all strings containing atleast two 1's
3.(1+€) (0+01)* all strings containing no consecutive 1's
4. 0*1[(0*10* 10*)* +0*]
@Lakshay Kakkar thanks for rectifying ,pls verfify now that 2nd and 3rd are reverse isomorphic and what about 4th?
