First, write a function class Solution { public int solution(int[] A); }that, given a zero-indexed array A consisting of N integers, returns the number of distinct values in array A. For example, given array A consisting of six elements such that:A[0] = 5 A[1] = 1 A[2] = 1 A[3] = 5 A[4] = 7 A[5] = 1the function should return 3, because there are 3 distinct values appearing in array A, namely 1, ..

Write a Java program to answer about the statistical information such as arithmetic mean, median, mode, and standard deviation of an integer data set. (The arithmetic median, median, and mode mean that the arithmetic average, mid-point of the distribution, and most frequent response, respectively.) The input data can be generated by random method or keyboard. Your program should display the outp..

The following is an example.Please enter the radius of a circle: 19 Area of a circle is 1134.114947 import java.util.*;public class Main {public static void main (String[] args) {var scanner = new Scanner(System.in);System.out.print("Please enter the radius of circle: ");int radius = scanner.nextInt(); //get radius from use..
