Which of these correctly describes the language accepted by this DFA? In all cases, we use the phrase "any string" to refer to strings drawn from the alphabet of this DFA: a, b, and c. Hint: remember that input can be an empty string b a,b,c a a 1 2 3 b,c Any string with at least one letter in which every occurrence of the letter a is followed by an occurrence of the letter c that comes before the next occurrence of the letter a. O Any string that contains the letter a followed by the letter c. O Any string in which there's an occurrence of the letter c somewhere after (to the right of) each occurrence of the letter a. O Any string that does not contain two a's together.

Write a C++ program that stores a list of fruits enumerated in Fruits.txt in a STL list of strings. You need to solve the following problem: · output all the fruits in your STL list · output all fruits that start with letter smaller than ‘m’ · output all fruits that contain less than 6 character symbols · calculate the numeric sum of all letters in each fruit and store your answer in a histogram of length 10 where each element contains a value that is a multiple of 500(e.g. your histogram vector contains 10 values and each value represents the numeric value of each fruit (Note: the grand total of values in you histogram should be equal to the total number of fruits · take all the fruits in Fruits.txt and store the in a STL set<string> container · output all the (unique) fruits in Fruits.txt · output the total number of entries in your set Fruits.txt = {pina, naranja, melon, cereza, uva, ciruela, limon, frutabomba, aguacate, platano, manzana, fresa, lechuga, nuez, sandia, mango,…
