WebNov 20, 2024 · Are two regular languages L and M equivalent? We can easily check this by using Set Difference operation. L-M =Null and M-L =Null. Hence (L-M) U (M-L) = Null, then L,M are equivalent. Membership of a CFL? We can always find whether a string exists in a given CFL by using an algorithm based on dynamic programming.
