@hem chandra joshi , please check it ..
After, eliminating ε-productions, unit production & useless symbols , grammar is :-
S ---> 00 | 0S0 | 1SS | 1S | 1 | ε ( empty string is in the language , so it can't be eliminated)
In CNF , it is :-
S' ---> S | ε
S ---> AA | AB | TC | TS' | 1
B ----> S'A
C -----> S'S'
A ------> 0
T ------->1
