- The block of compound statements (if or for statements) can be specified using curly braces or keywords approach such as end if or end for statements in different programming languages. Write in your own words, which approach can help in improving readability with giving some examples???Provide an illustration of how the Structured Programming Theorem may remove uncertainty caused by GOTO statements and simplify code that is too complicated. When you create an essay of the right length, be sure that you only use your own words.Syntactically different regular expressions may represent the same language. Consider regularexpressions over Σ = {0, 1}. Which of the following equations hold? (You don’t need to justifyyour answers.) 1. ε + 0 = ε + ε + 02. ε + 0∗ = 0∗3. (00 + 10)∗ = (01 + 11)∗4. 0 + ∅ = 0

Give a recursive definition for each of the problems stated below. For each problem clearly state the base case(s) and the recursive case(s). You do not need to implement these definitions in Java. exp(x,n) = xn , where both x and n are non-negative integers. E.g. exp(2,5) = 32 Assume we have a programming language that only allows conditionals (i.e. if statements), operations for +1 and -1, and recursive calls. How could the following function be defined recursively in that language? add(a,b) = a + b both a and b are non-negative integers. E.g. add(5, 7) = 12
- Can you help me with this probem and the parts that come along with it because i am confused I only need help with part A and part B. Can you please label the problem and can you do it step by step showing work and can you explain it as well. Question that I need help with:1.49 a. Let B = {1 k y| y ∈ {0, 1} ∗ and y contains at least k 1s, for k ≥ 1}. Show that B is a regular language. b. Let C = {1 k y| y ∈ {0, 1} ∗ and y contains at most k 1s, for k ≥ 1}. Show that C isn’t a regular language.can you help me with this questin because I don't understand it and I am having trouble with this can you do this step. by step and explain it in great detail and can you do something visual to help me understand it better. question:1.40 Recall that string x is a prefix of string y if a string z exists where xz = y, and that x is a proper prefix of y if in addition x 6= y. In each of the following parts, we define an operation on a language A. Show that the class of regular languages is closed under that operation. b. NOEXTEND(A) = {w ∈ A| w is not the proper prefix of any string in A}Note:- Need correct Answer and explanation also Else downvote again If G = ({S}, {a}, {S→ SS), S) find the language generated by G.
- I was wondering if you could elaborate on how the Structured Programming Theorem helps to eliminate GOTO ambiguity and spaghetti code. Use just your own words in an essay of the appropriate length that you will write.For each of the following statements, state whether it is True or False. 8. The intersection of a regular language and a nonregular language must not be regular. Group of answer choices True FalseWhy is it important in modern programming languages to include both pass-by-value & pass-by-reference? Why not just have one or the other? In your answer, describe the benefits of having each AND describe why it wouldn't be a good idea to have only one or the other.
