Without Formula: num = as.integer(readline(prompt = “Enter a number: “)) if(num < 0) { print(“Enter a positive number”) } else { sum = # use while loop to iterate until zero while(num > 0) { sum = sum + num num = num – 1 } print(paste(“The sum is”, sum)) } Output: Enter a

An Armstrong number, also known as narcissistic number, is a number that is equal to the sum of the cubes of its own digits. For example, 370 is an Armstrong number since 370 = 3*3*3 + 7*7*7 + 0*0*0. Program: num = as.integer(readline(prompt=”Enter a...

year = as.integer(readline(prompt=”Enter a year: “)) if((year %% 4) == 0) { if((year %% 100) == 0) { if((year %% 400) == 0) { print(paste(year,”is a leap year”)) } else { print(paste(year,”is not a leap year”)) } } else { print(paste(year,”is a leap year”))...

The factorial of a number is the product of all the integers from 1 to that number. For example, the factorial of 6 (denoted as 6!) is 1*2*3*4*5*6 = 720. Factorial is not defined for negative numbers and the factorial of zero is one,...

nterms = as.integer(readline(prompt=”How many terms? “)) # first two terms n1 = n2 = 1 count = 2 # check if the number of terms is valid if(nterms <= 0) { print(“Plese enter a positive integer”) } else { if(nterms == 1) { print(“Fibonacci sequence:”) print(n1) } else { print(“Fibonacci sequence:”) print(n1) print(n2) while(count

num = as.integer(readline(prompt = “Enter a number: “)) # use for loop to iterate 10 times for(i in 1:5) { print(paste(num,’x’, i, ‘=’, num*i)) } Output: Enter your number: 8 “8 x 1 = 8” “8 x 2 = 16” “8...

Sorting of vectors can be done using the sort() function. By default, it sorts in ascending order. To sort in descending order we can pass decreasing=TURE. Note that sort is not in-place. This means that the original vector is not effected (sorted). Only a...
