A prime number is called a Mersenne prime if it can be writtenin the form 2p - 1 for some positive integer p. Write a program that findsall Mersenne primes with p ≤100 and displays the output as shown below.(Hint: You have to use BigInteger to store the number because it is too big tobe stored in long. Your program may take several hours to run.)

Kth Largest Factor
A positive integer d is said to be a factor of another positive integer N if when N is divided by d, the remainder obtained is zero. For example, for number 12, there are 6 factors 1, 2, 3, 4, 6, 12. Every positive integer k has at least two factors, 1 and the number k itself.Given two positive integers N and k, write a program to print the kth largest factor of N.
Input Format: The input is a comma-separated list of positive integer pairs (N, k).
Output Format: The kth highest factor of N. If N does not have k factors, the output should be 1.
Constraints:
1<N<10000000000
1<k<600.
You can assume that N will have no prime factors which are larger than 13..

- Find the numbers that can be expressed as the product of two nonnegative integers insuccession and print them in increasing order. (For example, 30 is such a number as it can bewritten as the product of 5 and 6 (30=5x6), which are two numbers in succession.) The user shouldspecify a maximum value and the program should print all said numbers smaller than or equal tothat value.

- Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3. It can be show that for r E (-1/4, 1/4), g(x) = 1+ xg(r)? and therefore 1- VI 4.x g(x) = 2.x Use this formula and the known power series of V1+ x to write the first terms of the power series expansion of g, in the form g(x) = co + c1x + c2x2 + C3x + c4x* + ·..

- plz solve it asap ????????: Write a program for a game that consists of two players. The rule of the game is that player 1 inputs a random number from 1-100. Player 2 will input 5 numbers. If the summation of those numbers is equal to the number OR less than or greater than the number by 3 (+3 or -3), then player 2 wins. Otherwise, player 1 wins. Test Case 1 Input Player 1, enter a number: 50 Player 2, enter a number: 10 Player 2, enter a number: 10 Player 2, enter a number: 20 Player 2, enter a number: 5 Player 2, enter a number: 7 Output Player 2 wins Explanation: The summation of 10,10,20,5 and 7 is 52 which is greater than 50 by 2.

The user will input the diameter of the can end, and the height of the can. The volume of a cylinder is the well known formula: volume = area of the ends * height of cylinder. The twist is that a can of soup can not be completely filled to the top; only 95% of the volume can be filled with soup; the remaining 5% must remain empty to allow for expansion. NOTE: when computing the area, use pi to at least 5 significant digits (eg, 3.14159) or use the constant math.pi. You should define a function named soup_volume which takes two parameters, the diameter of the can in cm, and the height of the can in cm, in that order. The function should return a float value, which is the volume of soup that the can is able to hold. The function should not round the value, but when printing the value in the main program, format it to show only 2 decimal places. Example run of the program: Enter…arrow_forwardThe 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…arrow_forward
- Let n be a nonnegative integer. The factorial of n, written n!, is defined by 0!=1, n! =1*2*3*...n if n >= 1. For example, 4! = 1*2*3*4 = 24. Write a program that prompts the user to enter a nonnegative integer and outputs the factorial of the number.arrow_forwardQ1: Write a program that reads a set of N integers. Then, the program finds and outputs the sum of the even values and the sum of the odd values of them. For example: if the value entered for N=5, and the five integers are 3, 6, 2, 9, 7. Then the sum of even values (6+2 = 8), and the sum of odd values (3+9+7 = 19) Q2: Write a program that reads some numbers until it reaches a specific value (assume -1 is a stop value in this case). The program should find and outputs the average of all of the numbers (between 10...40) except the stop value (-1). For example: If the numbers look like: 12 5 30 48 -1. Then, the average of the numbers: (12+30)/2 = 21.arrow_forwardTransient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…arrow_forward
