| Question 19 |
Which of the following classes of languages can validate an IPv4 address in dotted decimal format? It is to be ensured that the decimal values lie between 0 and 255.
| RE and higher | |
| CFG and higher | |
| CSG 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.
