- Draw a DFA that accepts strings that do not contain two consecutive a's or two consecutive b's. Here, Σ = {a,b}. e.g. aba, bab, ababa, bababa, etc.Write in C Language Spilitology Yosef is a peculiar fellow. He introduced the idea to study a string by splitting it into two, and he called it Splitology. Why split a string? We do not know. Didn’t we say that Yosef is a weird one? Yosef is interested in one particular type of string, a palindrome. A palindrome is a string that is the same for both forwards and backwards. Example of palindrome strings are “ada”, “taat”, and “radar”. On the other hand, string such as “taman” is not a palindrome; notice that “taman” becomes “namat” if read backwardsand it’s not the same as “taman”. As the idea of Splitology is still new, Yosef is investigating whether a string can be split into two non-empty strings such that each string is a palindrome. For example, the string “malamini” can be split into “malam” and “ini” while both of them are palindrome. Another example is “ababab”. It can be split into “aba” and “bab”, and both of them are palindrome. Note that “ababab” can also be split into…Draw NFA that accepts the set of strings over {a, b} such that there should be at least one substring which starts and ends with a b and the number of symbols between these two b’s is divisible by 4. Example: abababaaaababab, babbaa (since 0 is divisible by 4), ababababbaa.l
- Given a string that may contain Azerbaijani letters, change them to the closest subsitude in English letters. (ü->u, ö->o, ğ->gh, ı->i, ə->a, ç->ch, ş->sh) Example: Üzüm => Uzum WRITE IN PYTHON PLEASEDraw a DFA that accepts All strings over {a, b} whose length is odd and start with 'a'(Program) Write a C++ program that accepts a string from the user and then replaces all occurrences of the letter e with the letter x.
- Write a regular expression for the set of strings over the alphabet {a, b} that have at least one a and at least one b. For example, aaaba and bbaba are strings in the set, but aaaa and bbb are not. Provide a brief explanation of how your expression works.A cryptogram is a coded message using alphabet substitution. For example, the letter "A" in the cryptogram might stand for the letter “Ż." You are to write a program that allows the program user to decipher cryptograms, like the following one. Your program should allow the user to change one letter and display the change, then change another letter and display the change etc. Here is a sample cryptogram to be decoded. String crypto.Part1 = "EKBQUDUHJ XK BCA AYGADDAMB KGENAHUEB UP" String crypto.Part2 = "BCA ZUQDR FDEIA BCA KBEWQK PUG UOQ PEODBK." String crypto.Part3 = "CUZALAQ PQXAMRK UOQ EODBK DXA MUB IM BCA" String crypto.Part4 = "KBEQK FOB XM UOQKADLAK."Write a C# Sharp program that compares strings taken as input by a user. compare the strings and print out the result i.e. if the first string is greater, smaller or equal to the second string.
- You have to construct a string “cmpmpcmpm” from a blank string. There are two ways to construct a string.1. Operation 1: You can add any character at the end of the string. It will cost you 5 points.2. Operation 2: You can copy any substring of string at the end of the string. It will cost you 6 points.The operations that you will choose to construct the string with minimum cost are:L={a"b"a" | n,m=1,2,3....} is given. ni m n Draw the derivation tree for the string aaaabbbaaaa.Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "!" to the end of the input string. i becomes 1 a becomes @ m becomes M B becomes 8 s becomes $ Ex: If the input is: mypassword the output is: Myp@$$word! Hint: Python strings are immutable, but support string concatenation. Store and build the stronger password in the given password variable.
