More than 2500 years ago, mathematicians got interested in numbers. Armstrong Numbers: The number 153 has the odd property that 1'+5+3= 1 + 125+27 153 Namely, 153 is equal to the sum of the cubes of its own digits. Perfect Numbers: A number is said to be perfect if it is the sum of its own divisors (excluding itself). For example, 6 is perfect since 1, 2, and 3 divide evenly into 6 and 1+2+3=6. Input File The input is taken from a file named number.in and which a sequence of numbers, one perline, terminated by a line containing the number 0. Output File A file number.out which contains all the the number read from the input file. These numbers are printed one perline followed by a sentence indicating whether the number is or is not armstrong number and whether it is nor not a perfect number. Sample Input 153 0 Sample Output 153 is an Armstrong number but it is not a perfect number. 6 is not an Armstrong number but it is a perfect number.

Sevens rule, zeros drool def seven_zero(n): Seven is considered a lucky number in Western cultures, whereas zero is what nobody wants to be. Let us briefly bring these two opposites together by looking at positive integers that consist of some solid sequence of sevens, followed by some (possibly empty) solid sequence of zeros. Examples integers of this form are 7, 77777, 7700000, 77777700, and 70000000000000. A surprising theorem proves that for any positive integer n, there exist infinitely many integers of such seven- zero form that are divisible by n. This function should return the smallest such seven-zero integer. Even though discrete math and number theory help, this exercise is not about coming up with a clever symbolic formula and the proof of its correctness. This is rather about iterating through the numbers of this constrained form of sevens and zeros efficiently and correctly in strictly ascending order, so that the function can mechanistically find the smallest working…
Problem 2: Write a java program that contains: a) The method public static int numberOccurrences(int a, int b) which returns an integer designating the number of appearance of the digit b in the number a. (b must between 0 and 9). b) Write a test program (main) that asks the user to enter an integer number and a digit then invokes (calls) numberOccurrences method. Sample run 1: Enter a number: 11941. Enter a digit: 1 The number of appearance of 1 in 11941 is 3 Sample run 1: Enter a number: 257 Enter a digit: 5
Artificial intelligence (Question - 6) ======================= One variation on the game of nim is described in Luger. The game begins with a single pile of stones. The move by a player consists of dividing a pile into two piles that contain an unequal number of stones. For example, if one pile contains six stones, it could be subdivided into piles of five and one, or four and two, but not three and three. The first player who cannot make a move loses the game.(6.1) Draw the complete game tree for this version of Nim if the start state consists of six stones.(6.2) Perform a minimax evaluation for this game. Let 1 denote a win and 0 a loss.
Python tic tac toe. Tic tac toe is a very popular game. Only two players can play at a time. Game Rules Traditionally the first player plays with "X". So you can decide who wants to go with "X" and who wants to go with "O". Only one player can play at a time. If any of the players have filled a square then the other player and the same player cannot override that square. There are only two conditions that may match will be a draw or may win. The player that succeeds in placing three respective marks (X or O) in a horizontal, vertical, or diagonal row wins the game. Winning condition Whoever places three respective marks (X or O) horizontally, vertically, or diagonally will be the winner. Submit your code and screenshots of your code in action. Hints : Have a function that draws the board Have a function that checks position if empty or not Have a function that checks player or won or not expected output:

Duplicate digit bonus def duplicate_digit_bonus(n): Some people ascribe deep significance to numerical coincidences, so that consecutive repeated digits or other low description length patterns, such as a digital clock blinking 11:11, seem special and personal to them. Such people then find numbers with repeated digits to be more valuable and important than all the ordinary and pedestrian numbers without any obvious pattern. For example, getting inside a taxicab flashing an exciting number such as 1234 or 6969 would be far more instagrammable than a more pedestrian taxicab adorned with some dull number such as 1729.Assume that some such person assign a meaningfulness score to every positive integer so that every maximal block of k consecutive digits with k>1 scores 10**(k-2) points for that block. A block of two digits scores one point, three digits score ten points, four digits score a hundred points, and so on. However, just to make this more interesting, there is also a special…
Blue-Eyed Island: A group of individuals live on an island until a visitor arrives with an unusual order: all blue-eyed people must leave the island as quickly as possible. Every evening at 8:00 p.m., a flight will depart. Everyone can see everyone else's eye colour, but no one knows their own (nor is anyone allowed to tell them). Furthermore, they have no idea how many people have blue eyes, but they do know that at least one person does. How long will it take for the blue-eyed individuals to leave?
Transcribed Image Text JAVA Programming Problem: In the game of "Assassin's Creed", you control a ship with a cannon which is attacking a large enemy Assassin's Creed, armed with many guns. Your goal is to destroy as many of the guns as possible. The battle field is a 2D Cartesian grid, where your cannon is located at the origin. The enemy Assassin's Creed is a horizontal line segment located from the coordinates (X1, Y) to (X2, Y). There are exactly (X2 - X1 + 1) guns on the ship, located at the integer points (X1, Y), (X1+1, Y), ..., (X2, Y). However, the problem is, you cannot always fire at a gun. There are supernatural rocks located at all points of the battlefield whose X and Y coordinates are both integers. In order to fire successfully at an enemy's gun, the line connecting your cannon and that gun must not go through any rocks. Develop a JAVA code to output the number of the enemy battleship's guns that your cannon can destroy. Test Case Result 1 2 2 -2
JAVA CODE PLS Rectangle by CodeChum Admin A rectangle can be formed given two points, the top left point and the bottom right point. Assuming that the top left corner of the console is point (0,0), the bottom right corner of the console is point (MAX, MAX) and given two points (all "x" and "y" coordinates are positive), you should be able to draw the rectangle in the correct location, determine if it is a square or a rectangle, and compute for its area, perimeter and center point. To be able to do this, you should create a class for a point (that has an x-coordinate and a y-coordinate). Also, create another class called Rectangle. The Rectangle should have 2 points, the top left and the bottom right. You should also implement the following methods for the Rectangle: display() - draws the rectangle on the console based on the sample area() - computes and returns the area of a given rectangle perimeter() - computes and returns the perimeter of a given rectangle centerPoint() -…

Their ages form an arithmetic sequence: the difference in ages between the middle child and youngest child is the same as the difference in ages between the oldest child and the middle child. For example, their ages could be 5, 10 and 15, since both adjacent pairs have a difference of 5 years. Given the ages of the youngest and middle children, what is the age of the oldest child? Input Specification The input consists of two integers, each on a separate line. The first line is the age Y of the youngest child (0
