5. (Longest common prefix) Write a method that returns the longest common prefix of two strings. For example, the longest common prefix of distance and disinfection is dis. The header of the method is: def prefix(s1, s2) If the two strings have no common prefix, the method returns an empty string. Write a main method that prompts the user to enter two strings and displays their common prefix. Enter the first string: distance

- Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.Write the countVowels function which counts the number of vowels using the string class as follows: int countVowels(const string& s) Write a test program that prompts the user to enter a string, invokes the countVowels function and displays the total number of vowels in the string.public String firstAndLast(String str) { //declare and create your first char //declare and create your second char //return your first and last char as a String }
- def swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.In the class String, the substring method inserts a String into another String. -True or -FalseWord Separator Write a program that accepts as input a sentence in which all of the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.” LINUX !#/bin/bash
- Problem Description. Arguments for the main method are passed as strings. Strings enclosed in quotation marks are considered as one argument. Write a program to parse arguments from a string. Arguments are separated by spaces. Enclosed strings are considered as one argument. Your program should prompt the user to enter a string and display the arguments, each per line, as shown in the following sample run. <input> Enter the arguments: a friend "good morning" "good afternoon" b <output> a friend good morning good afternoon b please provide the answer in JAVAPig LatinWrite a program that accepts a sentence as input and converts each word to “Pig Latin.” Inone version, to convert a word to Pig Latin, you remove the first letter and place that letterat the end of the word. Then, you append the string “ay” to the word. Here is an example:English: I SLEPT MOST OF THE NIGHTPig Latin: IAY LEPTSAY OSTMAY FOAY HETAY IGHTNAY in pythonData structure & Algorithum Java program Write code that accomplishes the following tasks: Consider two bags that can hold strings. One bag is name letters and contain several one-letter strings. The other bag is empty and is named vowels. One at a time, remove a string from letters. If the strings contain a vowel, place it into the bag vowels; otherwise, discard the string. After you have checked all of the strings in letters, report the number of vowels in the bag vowels and the number of times each vowel appears in the bag. 1. Declare and initialize Bag object named letters.2. Add several one-letter strings to letter object3. Declare and initialize another Bag object vowels.4. Removed a atring from the letters object5. If the removed string is a vowel, add that vowel to the vowel Bag object.6. Repeat removed and vowel check for entire Bag.7. Display the number of vowels in the Bag.8. Display the frequency of occurrences each vowel appears.
- pairRemoval(String,String,String) this is a public static function that takes three strings as arguments and returns a string. You will be given three strings, the first string is a sentence as text that contains at least one occurrence of left pattern and right pattern. The second and third arguments of the function are the left and right patterns respectively. Left pattern and right pattern are single characters strings that you are attempting to remove from the string. Your goal is to remove only the patterns when left pattern has an equal number of corresponding right patterns.}/*** Adds letterGuessed to the current String updateLetterBoard* @param usedLetterBoard* @param letterGuessed* @param first* @return updateLetterBoard with letterGuess appended. */public static String updateLetterBoard(String usedLetterBoard, char letterGuessed, boolean first) {return "";}Command Line Args Modify code below to accept the values for the key as command line arguments. Your program may assume the arguments given at the command line are integers. If there are no arguments, print a message. If there is at least one argument, compute and print the average of the arguments. Note that you will need to use the parseInt method of the Integer class to extract integer values from the strings that are passed in. If any non-integer values are passed in, your program will produce an error, which is unavoidable at this point. import java.util.Scanner;import java.text.NumberFormat; public class Quizzes {// ----------------------------------------------// Read in the number of questions followed by// the key, then read in each student's answers// and calculate the number and percent correct.// ---------------------------------------------- public static void main(String[] args) {int numQuestions;int numCorrect;String anotherQuiz;int answer;NumberFormat percent…
