|
RE and higher
|
|
|
CFG and higher
|
|

|
|
Recursively enumerable language

Question 19 Explanation:
To ensure that decimal value lie between 0 and 255 we can make finite automata as
number of decimal values between 0 and 255 is finite. So RE (regular) and higher is correct.
number of decimal values between 0 and 255 is finite. So RE (regular) and higher is correct.
