- f) A new element can be added in a const array in Javascript. True/False.An array index starts with -1 1 0. 2.Functions with 2D Arrays in Java Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9
- Develop the program so that the user will be able to dynamically enter any amount of numbers. Afterwards, identify which of these elements are of perfect squares. Then display the identified perfect squares together and their sumAn array index can be of data type; a. int b. float O c. double O d. any type1Code a JavaScript callback function for the Array.map method to ('Yu Yamaguchi') evaluate an array of integersidentify the integers that are Prime numbersreturn the Prime numbers in the new array 2 Code a JavaScript callback function for the Array.reduce method to evaluate an array of integersdetermine the smalles integerreturn the smalles integer Note: if there are identical integers, the function is to return the last one.
- Find the average of a large array of integers using ForkJoin Framework. You may randomise the array elements valueJavascript Write the function popAndShift(). The function has to first print the the contents of the arrays array1 and array2. After this, the elements of array2 will be deleted, alternating between the .pop() and .shift() methods (starting with .pop()), while adding the removed values to the end of array1. Finally, the contents of array1 will be printed. Note! The automatic test takes care of assigning values to the arrays. Example output: First array: first,second Second array: third,fourth Resulting array: first,second,fourth,third The verification of program output does not account for whitespace characters like "\n", "\t" and "Create an indexception value of unique consonants and unique vowels.This is the Input: String of the name that was given below. It must be case sensitive.Steps:Step A: In every unique vowel of a name, you need to get the first index of that vowel from the original string.Step B: In each vowel index you get from step A, you will get the unique consonant from that position. if the index is out of scope of the consonant array, ignore that vowel index.Step C: In each unique consonant that you get from step B, you need to get the first index of that consonant from the original string.Step D: You will the value of indexception by adding all index you get from step C.output must be like this: > 2 lists that consist of unique vowels and unique consonants> vowel, the vowel index, the consonant, the consonant indexfinal ouput> total indexception value of the name that was given. ------Input "Tricia O. Reyes"Output:Name: Tricia O. ReyesVowels: ['a', 'e', 'i', 'o']Consonants: ['T', 'r',…
- Declare an array that represents 100 students. Assign the examscores between 0 and 100 randomly into this array. Write amethod and display that assigns letter grade equivalents of theexam scores to a second array. Display the number ofunsuccessful students.The grade scala is as follows:100 – 90 : A89 – 80 : B79 – 70 : C69 – 60 : D59 – 0 : F (unsuccessful) (Write in java)javascript Define a function, myIncludes, that accepts two parameters: an array and a searchValue. myIncludes should return true if the searchValue is an element in the array. Otherwise, myIncludes should return false. example myIncludes([10, 20, 30], 20); // => true myIncludes(['apples', 'bananas', 'citrus'], 'pears'); // => false19. A two-dimensional array is frequently called a matrix and such a matrix is usually displayed in a row X col format. Write a method, which displays a 3 X 4 matrix to the monitor, in a format like: sample data: 10 11 12 13 14 15 16 17 18 19 20 21 Complete method displayMatrix below. // precondition: // postcondition: 11 mat is a non-empty 2D array of int values. displayMatrix displays the elements of 2D array mat in Row X Col format. public static void displayMatrix(int[][] mat)
