The language composed of all strings over the alphabet {a,b} of the form: zero or more a's followed by zero or more b's, i.e., {"", a, b, aa, ab, bb, aaa, aab, abb, bbb, ...}, where "" is the empty string, is a regular language: show why this is. Note that you may use any line of argument on regular languages, e.g., by showing that it can be constructed using the properties ("Regular Language: a formal definition"), or by drawing the finite state automaton (FSA), or giving its description.

Q1 Suppose that language LC {a}*. For which of the following options does L = L*? OL= {A, a, aa, aaa, aaaa, ...} (any length string of a's) OL= {A, aa, aaaa, aaaaaa, ...} (even length strings of a's) OL= {a, aaa, aaaaa, ...} (odd length strings of a's) OL= {A} (only the empty string)
Develop an algorithm and write a C++ program that counts the letter occurrence in the string; make sure you use call by reference to the array of a class with letter and count as private member attributes when return from parse function. For the class member methods, provide the public accessor and modifier as well as print functions for the private member attributes. Write a test program that reads a C-string and displays the number of letters [a-z] and number of numbers [0-9] in the string. In addition to that, you need to output the histogram of the letter and count array. Here is a sample run of the program: <Output> Enter a string: 2023 is coming The number of letters in 2023 is coming is 8 The number of numbers in 2023 is coming is 4 ---- Histogram ---- Char Count 0 1 2 2 3 1 c 1 g 1 i 2 m 1 n 1 /* not a completed output */ <End Output>

IN JAVA Write a function that takes in user input as a string. For all characters which are numeric, double its value and, if it is two digits, then replace it with the sum of its digits (e.g., 6 → 12 → 3 whereas 3 → 6). For all characters which are in uppercase, replace it with lowercase. For all characters which are in lowercase, replace it with uppercase (e.g., m → M and N → n). The program should keep asking the user to enter strings until they either enter ‘q’ or ‘Q’.

DateType keeps only the integer representation of the month,day, and year. When a month is wanted in string form, the string iscalculated. An alternate approach would be to add a string field tothe date and calculate and store the string representation in theInitialize function. Which methods would have to bechanged? Would this change make the use of an if statement tofind the appropriate string more or less attractive? Write the code in C++for this if statement.
