Fleet class:
Instance Variables
An array that stores Aircraft that represents Delta Airlines entire fleet
A variable that represents the count for the number of aircraft in the fleet
Methods:
o Constructor-One constructor that instantiates the array and sets the count to aero
readFile()-This method accepts a string that represents the name of the file to be
read. It will then read the file. Once the data is read, it should create an aircraft and
then pass the vehicle to the addAircraft method. It should not allow any duplication
of records. Be sure to handle all exceptions.
o writeFile()-This method accepts a string that represents the name of the file to be
written to and then writes the contents of the array to a file. This method should
call a sort method to sort the amay before writing to it.
sortArray()-This method returns a sorted array. The array is sorted by registration

C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary). You are responsible for…

- Palindrome Checkercreate a JavaScript program that checks if phrasesentered by the user are palindromes. A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward, such as “SIR”,“raceBIKE”, “Never odd or even”, “20/1/20”. The program should prompt the user to typein a phrase that is at least three characters long, and then tell the user whether the phrasewas a palindrome. Note, the decision should be based solely on letters and numericaldigits, and so it should not consider other characters, such as spaces or exclamationmarks, even though these might be entered by the user. when checking palindromes.A.
