The ancient Greeks classified numbers geometrically. For example, a number was called "triangular" if that number of pebbles could be arranged in a symmetric triangle as shown in the figure below. The first ten triangular numbers are 1, 3, 6, 10, 15, 21, 28, 36, and 45. Write a program that takes as input a number N and prints whether it is triangular or not. T,=1 T = 3 T;- 6 T,=10 Ts= 15

A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Area = ( n * s2 ) / (4 * tan( π/n) Here, s is the length of a side. Write a program that prompts the user to enter the number of sides and their length of a regular polygon and displays its area.
A positive integer is called a perfect number if it is equal to thesum of all of its positive divisors, excluding itself. For example, 6 is the first perfectnumber because 6 = 3 + 2 + 1. The next is 28 = 14 + 7 + 4 + 2 + 1. Thereare four perfect numbers < 10,000. Write a program to find all these four numbers.
Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied across each. Their equivalent resistance Reg is related to the values R1, R2, ..., Rn by: 1 1 1 1 + +...+ R R R, R. "eq Write a program that prompts the user to enter the resistance of n resistors. The user should be prompted continuously by using a while loop until a zero or negative value is entered (the program should count the number of resistors n entered by the user and store the values in an array). Use another separate loop to print the resistance values entered by the user and the equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.
Write a program that reads an integer and displays all its smallest factors, also known as prime factors. For example, if the input integer is 120, the output should be as follows: 2, 2, 2, 3, 5
Write a program that first reads the value n, which is the number of numbers to average. It should then read the n positive (float) numbers, average them, and display the average. ENTRYAn integer n and then the n floating numbers EXIT The average of the n numbers read. Example of program execution: Input 3 Entry 2.5 Entry 3.8 Entry 4.6 Output3.633333333333333
Write a program that inputs a number and checks whether it is a perfect number or not. A perfect number is the number that is numerically equal to the sum of its divisors. For example, 6 is a perfect number because the divisors of 6 are 1, 2, 3 and 1+2+3=6
Description A mathmatician Goldbach's conjecture: any even number(larger than 2) can divide into two prime number’s sum.But some even numbers can divide into many pairs of two prime numbers’ sum. Example:10 =3+7, 10=5+5, 10 can divide into two pairs of two prime number. Input Input consist a positive even number n(4<=n<=32766). Output Print the value of how many pairs are this even number can be divided into. Sample Input 1 1234 Sample Output 1 25
Write a program that reads an integer and displays all its smallest factors in an increasing order. For example, if the input integer is 120, the output should be as follows: 2, 2, 2, 3, 5.
Code in Java using Do-while Loop Write a program that accepts an integer input. If the integer is positive, print the values from the positive integer down to zero. Otherwise, if it is negative, print the values from the negative integer up to zero. Separate each number with a space. Input 1. One line containing an integer Output Enter a number: 5 5 4 3 2 1 0
You have been asked to write a program to play rock-paper-scissors. Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)
Write a program that reads an integer between 0 and 1000 and multiplies all the digits in the integer. For example, if an integer is 932, the multiplication of all its digits is
The equation of a straight line is written as y = mx + b where m is the slope of the line and b is the value of y when x = 0. If there are two coordinate points of the line are given, then it is very easy to compute the line equation. Also you can find the distance between two points. Problem: Write a program to compute lines equation for a set of lines. The number of lines is read from the user. Each line is computed by generating two points randomly using Point2D API. In addition, distance between two points is computed. The program should display a table which include all information about each line. See sample runs below. Take into consideration: 1. Number of generated lines should be greater than zero. 2. Two point objects are constructed only once. Then just update the location of two points for each line using Point2D API methods. 3. x and y values of each point are generated randomly to be less than 100 and greater than 0. 4. Compute the distance between two points using…
