Use the following header: int indexOfLargestElement(double array[], int size)arrow_forward(Locate the largest element) Write the following function that finds the location of the largest element in a two-dimensional array. void 1ocateLargest(const double a[][4 ], int 1ocation[]) The location is stored in a one-dimensional array location that contains two elements. These two elements indicate the row and column indices of the largest element in the two-dimensional array. Write a test program that prompts the user to enter a 3 × 4 two-dimensional array and displays the location of the largest element in the array.arrow_forward(Random sentences and story writer) Write an app that uses random-number generation to create sentences. Use four arrays of strings, called article, noun, verb andprepostion. Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article, noun.As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forward

- (Algebra: perfect square ) Write a program that prompts the user to enter an integer m and find the smallest integer n such that m * n is a perfect square. (Hint: Store all smallest factors of m into an array list. n is the product of the factors that appear an odd number of times in the array list. For example, consider m = 90, store the factors 2, 3, 3, 5 in an array list. 2 and 5 appear an odd number of times in the array list. So, n is 10.) Sample Run 1 Enter an integer m: 1500 The smallest number n for m x n to be a perfect square is 15 m x n is 22500 Sample Run 2 Enter an integer m: 63 The smallest number n for m x n to be a perfect square is 7 m x n is 441 Class Name: Exercise11_17 Answer is : import java.util.Scanner; public class Squares { public static void main(String[] args) { Scanner scan = new Scanner(System.in); //instantiation of Scanner that will take inputs from the keyboard //the try catch block below is for trapping error with the input try {…arrow_forward(Java 4 intellij) Part1: Read an integer input from the user and save it to a variable 'size'. - Use the variable 'size' to initialize an array of length size - Next read in integer inputs from the user and save each incoming integer to the next available position in your array. - Continue until your array is full. - Note: You will need to conditionally check if you have received the number of inputs you need from the user to fill the array. Print the contents of the full array. Part 2: Create a method which generates and prints “n” random numbers. The method takes an int parameter indicating how many random numbers to print. Use a loop. arrow_forward(See attached photo) Please explain the flow of finding the exact running time of the program.
