Write a Java 7 program with proper whole code and Explatation too,,. & Dont use JAVA8...   Shil got an array of N integers as a present on his birthday. But he didn't liked it. Shil wants to make this array beautiful. Shil considers an array A1,A2,A3 . . . AN beautiful if A1 > AN. Inorder to make it beautiful Shil can swap any two numbers in the array. Also Shil can perform this operation any number of times on any adjacent pairs of integers in the array A.Find the number of ways in which Shil can make this array beautiful.Two ways are considered same if resulting array after making all the swaps have same A1 and AN. Input First line of input contains an integer N denoting the number of elements in an array A. Next line of input contains N space separated integers denoting A1,A2,A3 . . . AN respectively. Output Number of ways in which you can make given array beautiful. Constraints 1 ≤ N ≤ 106 1 ≤ Ai ≤ 106 SAMPLE INPUT     5 1 4 3 2 5   SAMPLE OUTPUT     10 Explanation Total number of ways are (5,1),(4,1),(3,1),(2,1),(5,2),(4,2),(3,2),(5,3),(4,3),(5,4). First number in above pair is A[1] and second number is A[N].Note that two ways are considered same if A[1] and A[N] are same in resulting array after swaps.

Implement the Board class. Make sure to read through those comments so that you know what is required.   import java.util.Arrays; import java.util.Random; public class Board { // You don't have to use these constants, but they do make your code easier to read public static final byte UR = 0; public static final byte R = 1; public static final byte DR = 2; public static final byte DL = 3; public static final byte L = 4; public static final byte UL = 5;   // You need a random number generator in order to make random moves.  Use rand below private static final Random rand = new Random(); private byte[][] board;     /** * Construct a puzzle board by beginning with a solved board and then * making a number of random moves.  Note that making random moves * could result in the board being solved. *  * @param moves the number of moves to make when generating the board. */ public Board(int moves) { // TODO }   /** * Construct a puzzle board using a 2D array of bytes to indicate the contents *…

The java program ArrayTest.java is intended to do the following: • Fill the array a with integer values input from the file ints.txt. • (Shift-right) Shift the elements of a to the right one position and put the last element of array a in the first position in a (wrap around). Example: if a originally contained (1, 2, 3, 4} then the resulting array a would be (4, 1, 2, 3} What command would be given on the command line to redirect the input to the program ArrayTest to come from the text file ints.txt?

Given your array declared above, and assuming your program has already read in a certain number of Complex values into that array, we'd like to take the average of these Complex values. It may help if you also knew that the Complex class has this method for adding two Complex objects: Complex Complex::add(const Complex & b) const; and a method to divide a Complex object by a floating-point value: Complex Complex::divide(double n) const; Now, show your code in C++ to average all the elements in your array of Complex numbers. (Hint: What is the data type of the average of two or more Complex numbers?)
