Revorse the vewels def reverse_vowels(text): Given a text string, create and return a new string constructed by finding all its vowels (for simplicity, in this problem vowels are the letters found in the string 'aeiouAEIOU') and reversing their order, while keeping all other characters exactly as they were in their original positions. However, to make the result look prettier, the capitalization of each moved vowel must be the same as that of the vowel that was originally in the target position. For example, reversing the vowels of 'Ilkka' should produce 'Alkki' instead of 'alkkI'. Applying this operation to random English sentences seems to occasionally give them a curious pseudo-Mediterranean vibe.Along with many possible other ways to perform this square dance, one straightforward way to reverse the vowels starts with collecting all vowels of text into a separate list, and initializing the result to an empty string. After that, iterate through all positions of the original text.…
Integers numberOfParts, required Groups, and invalid Groups are read from input. If numberOfParts is 21 or more, then add 3 to requiredGroups. Otherwise, add 6 to invalidGroups. ► Click here for examples 3 public class GroupSurvey { 4 public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int numberOfParts; int requiredGroups; I int invalidGroups; 345679 8 9 10 11 12 13 14 15 16 17 18 19 20 } numberOfParts = scnr.nextInt (); requiredGroups = scnr.nextInt (); invalidGroups = scnr.nextInt (); /* Your code goes here */ if(numberOfParts>21){ requiredGroups= System.out.println(requiredGroups); System.out.println(invalidGroups);
Solution in Java Create a function that takes an array of increasing letters and return the missing letter. Examples missing Letter (["a", "b", "c", "e", "f", "g"]) → "d" missing Letter (["O", "Q", "R", "S"]) → "P"
Javascript Use a for/of loop to iterate over the array of students. For each student, use a template literal to print out their name, age, and major in a formatted string. (e.g. John is 18 years old and is studying Computer Science.) Within the template literal, use object dot notation to access the name, age, and major properties of the student object. Use a console.log() to print out the formatted string for each student. Test the code by running it and verifying that it prints out the details of each student in a formatted string.============================================================================== const students = [ { name: "John", age: 18, major: "Computer Science" }, { name: "Newton", age: 19, major: "Mathematics" }, { name: "Barry", age: 20, major: "Physics" }, ]; // Iterate through the array of objects students using for/of // Print a message to the console that includes the student's name, age, and major // Example: John is 18 years old and…
