Answer:
Check Explanation
Explanation:
A) the string (abbba) is not a word in this language because in this language, each b must preceded or followed by an a. Three consecutive b's are just not possible.
B) All the words with 3 letters in this language
aaa
aab
aba
baa
C) 5 words with four letters from this language. I'll write as many as possible to make things as easy as possible.
aaaa
aaab
aaba
baab
baba
baaa
abaa
abab
abba
D) This is the language of words without bbb, with every bb preceded and followed by an a (that is, no word can start or end wilth bb). All non-empty strings contain at least one a (so b and bb together are not allowed!).
Hope this Helps!!!
I can’t see the answer choices but I would like to say it’s JPEG am not sure. Could you at least provide the answer choices? Thanks!
Answer:
A generalized class used only to create related derived classes
Explanation:
An abstract class is a class which cannot be instantiated on its own. It is defined using an abstract keyword. However, an abstract class can be inherited from and the derived class can actually be instantiated. For example:
abstract class A{
}
class B extends A{
void test(){
}
}
Here class A is an abstract class, while class B inherits from A. Now we can create an instance of class B as follows:
B b = new B();
b.test();
Number 1 and 4 are the same? I agree with your answers.
sure! what do you wanna chat about?
