Fill out the table for executing the polynomial-time dynamic programming algo-
rithm for deciding whether the string 1001 is in the context-free language generated by the
following CFG. Fill the table completely-do not stop the algorithm early. (Note: This CFG
is not quite in Chomsky Normal Form since A appears on the right-hand side of a rule, but
|the same algorithm still works.)
A + BC | CC
B + BA | 0
с + АВ | Вв | 1
PLease answer both question with clear explanastion. Thanks in advance
1. What is the regular expression for the language, over alphabet {a, b}, of strings that start and end with the substring ab and contain one or more repetition of the substring bab.2. Describe in English the language associated with the following regular expression: (a+b)*a(a+b)*a*(a+b)*a(a+b)*
. Prove that the intersection of two context-free languages is not necessarily context-free. This is unlike the
case of regular languages which are closed under intersections. Hint: Do something similar to what we did on
Activity #21 to show something about two of the languages below and then use what we proved in class about
the remaining language. Write several sentences to explain your reasoning.
L₁ = {ww has the form a"b"c" for some whole numbers n and m}
L2 = {ww has the form amb"c" for some whole numbers n and m}
L3 = {w|w has the form a"b"c" for some whole number n}

Use a proof by construction with generalized state diagrams. 1. Prove that regular languages are closed under the star-closure operation.arrow_forwardAccording to Wikipedia, it makes the language "sweeter" for human use: things can be expressed more clearly, more concisely, or in an alternative style that some may prefer. Out of the list below, which is/are the example(s) of "syntactic sugar" given in class? I. Use of for-loop instead of while-loop to avoid forgetting the counter increment II. If r1 and r2 are Rat objects, we want to write r1 + r2 instead of r1.operator+(r2) III. Use of the "[]" to get to elements of an array IV. Use of *(a+i) instead of a[i]. Answer choices: a.)

- For each of the following languages, determine whether or not it is context-free. You must justify youranswer.

- For this exercise, we will work on a regular grammar to recognize a comment in a C++ or Java program. A comment starts with /* and ends with */ and anything else in between can be ignored. We won't consider the case of nested comments. Keep in mind that you can have any number of * characters at the beginning, at the end, and in between. • Write a regular grammar recognizing such comments. • Draw the finite state machine for this grammar. • Draw a table for this grammar such as the ones for table-driver scanners in the class notes and in the book.arrow_forwardCreate a Turing Machine in JFLAP that decides the language. You may have "multiple final states" for readability (final states cannot have any outgoing transitions). You do not need to show the reject state.
