Construct sequence using a specified number of integers within a range. The sequence must be strictly increasing at first and then strictly decreasing. The goal is to maximize the sequence array elements starting from the beginning. For example, [4, 5, 4, 3, 2] beats [3,4,5,4,3] because its first element is larger, and [4, 5, 6, 5, 4] beats [4,5,4,3,2] because its third element is larger. Given the length of the sequence and the range of integers, return the winning sequence. If it is not possible to construct such a sequence, return -1. Write an algorithm that returns a winning sequence and -1 if the sequence is not possible. Input The input to the function/method consists of three arguments: num : an integer representing the size of sequence to create lower End : an integer representing the lower end of integer range upperEnd : an integer representing the upper end of integer range.

Explanation:

The following code is written in Java. It first creates a function that takes in the three parameters to create the sequence, if the sequence is valid it returns the created sequence, otherwise it prints -1 and returns an empty array. The second function called compareSequences takes in to sequences as parameters and compares them, printing out the winner. A test case has been provided in the main method and the output can be seen in the image below.

import java.util.Arrays;

class {

public static void main(String[] args) {

int[] seq1 = createSequence(5, 4, 2);

int[] seq2 = createSequence(5, 3, 3);

System.out.println("Winner: " + Arrays.toString(compareSequences(seq1, seq2)));

}

public static int[] createSequence(int num, int upperEnd, int lowerEnd) {

int[] myArray = new int[num];

int middle = (int) Math.floor(num/2.0);

myArray[0] = upperEnd;

myArray[num-1] = lowerEnd;

int currentValue = upperEnd;

for (int i = 1; i < num-1; i++) {

if (i <= middle) {

myArray[i] = currentValue + 1;

currentValue += 1;

} else {

myArray[i] = currentValue - 1;

currentValue += 1;

}

System.out.println(Arrays.toString(myArray));

if (myArray[num-2] < lowerEnd) {

System.out.println("-1");

int[] empty = {};

return empty;

} else {

return myArray;

}

public static int[] compareSequences(int[] seq1, int[] seq2) {

int lowestLength;

if (seq1.length > seq2.length) {

lowestLength = seq2.length;

} else {

lowestLength = seq1.length;

}

for (int i = 0; i < lowestLength; i++) {

if (seq1[i] > seq2[i]) {

return seq1;

} else if (seq1[i] < seq2[i]) {

return seq2;

}

if (seq1.length > seq2.length) {

return seq1;

} else {

return seq2;

}

The “rule of 72” is used to approximate the time required for prices to double due to inflation. if the inflation rate is r%, then the rule of 72 estimates that prices will double in 72/r years. for instance, at an inflation rate of 6%, prices double in about 72/6 or 12 years. write a program to test the accuracy of this rule. for each interest rate from 1% to 20%, the program should display the rounded value of 72/r and the actual number of years required for prices to double at an r% inflation rate. (assume prices increase at the end of each year.)

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.

Write a program that keeps asking the user for new values to be added to a list until the user enters 'exit' ('exit' should not be added to the list). these values entered by the user are added to a list we call 'initial_list'. then write a function that takes this initial_list as input and returns another list with 3 copies of every value in the initial_list. finally, inside print out all of the values in the new list. for example: input: enter value to be added to list: a enter value to be added to list: b enter value to be added to list: c enter value to be added to list: exit output: a b c a b c a b c note how 'exit' is not added to the list. also, your program needs to be able to handle any variation of 'exit' such as 'exit', 'exit' etc. and treat them all as 'exit'.
