TM, RE, Non-RE Thanks in advance Tell whether the following language L is recursive, RE-but-not-recursive, or...
true or False with prove? (f) ___ NP =co-NP (g) The complement of any recursive language is recursive. h) The grader's problem is decidable. We say programs Pi and P are equivalent if they give the same output if given the same input. The problem is to decide whether two programs (in C++, Pascal, Java, or some other modern programming language) are equivalent. )Given any CF language L, there is always an unambiguous CF grammar which generates L 6)Given any...
Hi please help with this program C++ language thanks Write a recursive solution to solve the Partition problem. Partition: Given a set A of n integers a, a, .....a., can you find a subset A_1 of integers such that the sum of the Integers in A_1 is half of the Sum of all the n Integers (that Is, sigma_alpha 1 A_1 a_i)? Input: 1.Number of integers of set A: n 2.n Integers: a_1 a_2, a_n. Output: Print out yes if...
help with all of them please thanks in advance 1. Determine whether the given statement is a tautology, a contradiction or neither. Justify your answer. (p Aq) → (pVq)) 2. Determine the intersection and the union of the intervals (3,5), [4, 7] and [5, 8). 3. For each positive number t, let At be the interval (-2, t]. Determine the union Ut>O At and the intersection n t>o At of the family {At t>0}. 4. prove that the set {5kke...
3. Decide whether the following language is a CFL. If your answer is “yes”, construct a CFG; if your answer is “no”, prove it using the pumping lemma. L = {xayb | X, Y E {a,b}* and x, y has the same number of a’s}.
Hi, I need help with part A. Please show all the work, thanks. Decidability 1. Which of the following problems is decidable? Why? a) Given a TM M and a stringy, does M ever write the symbol # on its tape on input y? b) Given a context free grammar G over (a, b), does G generate all the strings of the anguage fa, b* of length s 381? c) Given a context free grammar G over (a, b), does...
it must be in C programming language , Thanks in advance! [2D array] [50 pts] In this question, you will create a 2-D array with name arr that stores the first 36 non-negative numbers (0 to 35). You have to follow the following guidelines: • You cannot manually enter all 36 numbers by hand. If you do that you will get from this part. You have to use loop/loops to define that array. (15 pts] • You should be printing...
I need help with question 2, 3 and 4 please. Thanks in advance. Answer the following questions: 1. Prove that any polynomial of degree k is O (nk 2. By finding appropriate values ofc and no, prove that: f(n) 4 n log2 n + 4 n2 + 4 n iso(n2). 3. Find functions fi and fi such that both fi(n) and /i(n) are O(g(n)), but fi(n) is not OG(n)) 4. Determine whether the following statements are true or false. Briefly...
Write a recursive function called freq_of(letter, text) that finds the number of occurrences of a specified letter in a string. This function has to be recursive; you may not use loops! CodeRunner has been set to search for keywords in your answer that might indicate the use of loops, so please avoid them. For example: Test Result text = 'welcome' letter = 'e' result = freq_of(letter, text) print(f'{text} : {result} {letter}') welcome : 2 e and A list can be...
The question of validity is to answer the question of whether for a Boolean expression consisting of n variables . There is a combination of values of variables that make the result of the expression true or not. In this phrase each The variable can be simple or contradictory. Force brute method of all compounds . Creates and evaluates the possible and the first time the result is true (if it is) the answer to the problem Come and stop...
Please answer all parts of the question and clearly label them. Thanks in advance for all the help. 5. An eigenvalue problem: (a) Obtain the eigenvalues, In, and eigenfunctions, Yn(x), for the eigenvalue problem: y" +1²y = 0 '(0) = 0 and y'(1) = 0. (5) Hint: This equation is similar to the cases considered in lecture except that the boundary conditions are different. Notice how each eigenvalue corresponds to one eigenfunction. In your solution, first consider 12 = 0,...
