C is context free lamguage, we can push as many a's and again as many b's and for every c we push we will pop one b and for every d we push we will pop a a. A is classic CSl. 0 votes 0 votes shayal chhabra commented Jan 14, 2017 reply Follow Share D is not DCFL here as we need to check the palindrom of a string but middle symbol is not differently known here x is given as middle variable but not it belongs to 0,1 as whole language is also belongs to 0,1 so it is ncfl. 0 votes 0 votes Please log in or register to add a comment.
