Write a recursive method for the sum of n integers? Recursion is a method calling itself. Such a method is said to be a recursive method. A recursive algorithm is similar to Mathematical Induction problems. We assume that there is a solution for a base case, and we will prove the result for the general […]

Program Description Write a java program to calculate the mean and standard deviation of the given population of numbers. IPO Chart Input We will take input from the user for the population of numbers. Process mean = (x1 + x2 +… xn)/n sd = sqrt( ((x1- mean)^2 + (x2- mean)^2 +…+ (xn- mean)^2 )/n) Output […]
Program Description Write a java program to compute the factorial of a given number. IPO Chart Input We will take input from the user for the given number. Let’s call this number n. Process Compute n! n! = (n)*(n-1)*(n-2)*…… * 1 Output The program will output n! for the given n number. Java Program […]
