- Randomize_it Write a function in C++ that takes an array as a parameter and then randomize that array, i.e. shuffles the position of the elements in random order. To randomize the array your function should perform random 100 swaps of any two elements in the array. Return the randomized array from the function.vector<int> randomize(vector<int> input){// code here}arrow_forwardtest_var = 'AAMMTTMT';//test_var is testing variable takenarray = test_var.split('');//string is split into the array function SWAP(TAM, i, j)//function to swap{temp = TAM[i];TAM[i] = TAM[j];TAM[j] = temp;}function sort_AMT(TAMUK)//function to sort the array{for(i = 0; i<TAMUK.length;i++){for(j = 0; j<TAMUK.length-1;j++){if(TAMUK[i]<TAMUK[j])SWAP(TAMUK,i,j);}}console.log(TAMUK);} sort_AMT(array);//function call How to write an HTML code for this javascript result/output? where the result will be displayed in HTML page.arrow_forward// MichiganCities.cpp - This program prints a message for invalid cities in Michigan. // Input: Interactive // Output: Error message or nothing #include <iostream> #include <string> using namespace std; int main() { // Declare variables string inCity; // name of city to look up in array const int NUM_CITIES = 10; // Initialized array of cities string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"}; bool foundIt = false; // Flag variable int x; // Loop control variable // Get user input cout << "Enter name of city: "; cin >> inCity; // Write your loop here // Write your test statement here to see if there is // a match.

- Description of the assignment: Your program should read in a set of grades (that are all integers) entered by the user. The user will signify the end of the list of grades by entering -999. Do NOT process this value. You can assume that the user will enter at least three grades and not more than 100 grades, all of which will be integers in between 0 and 100, inclusive. For the set of grades, your program should compute the minimum value, print this out to two decimal places and remove it from the data. Then your program should compute the maximum value, print it out to two decimal places and remove it from the data. Then, your program should calculate the mean and standard deviation for the remaining set of grades, and print these out to two decimal places. Finally, a histogram for this data (without the highest and lowest grades) should be printed out as well. Your program should include the following functions: void readGrades (double grades [], int *n); /* This function reads an…arrow_forwardC++ Write a program that populates an array with numbers and allows the user to run some actions on the array. Your array will be initialized in your main function to a constant global value, MAX_SIZE, which should be set to 20. To perform the subtasks, you will be writing three functions: fillArray: This function takes in an array of integers and a reference to an integer representing the number of filled elements. In this function, the user is prompred to enter a positive number that is no greater than 20, and this input will loop until the user enters a legal value. This value will be filled inside of the reference parameter mentioned above. From here, the array will be filled up to "value" elements with randomly generated numbers between 1 and 100. Make sure to set the random seed to 20 at the start of main() for consistent results. displayArray: This function takes in an array of integers and an integer representing the number of filled elements.

- JAVASCRIPT Write the function divideArray() in script.js that has a single numbers parameter containing an array of integers. The function should divide numbers into two arrays, evenNums for even numbers and oddNums for odd numbers. Then the function should sort the two arrays and output the array values to the console.arrow_forwardProgramming language : Swiftarrow_forwardMatrix Multiplication• Write a multiplication function that accepts two 2D numpy arrays,and returns the product of the two. This function should test that thearrays are compatible (recall that the number of columns in the firstmatrix must equal the number of rows in the second matrix). Thisfunction should test the array sizes before attempting themultiplication. If the arrays are not compatible, the function shouldreturn -1. solve in pythonarrow_forward
- In C++ language Write a function that takes a 1 Demensional array and an integer n and reutrns the number of times 'n' appears in the array. If 'n' does not appear in the array, return -1.arrow_forward1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.arrow_forwardPrompt: In Python language, write a function that applies the logistic sigmoid function to all elements of a NumPy array.
