Answer for While Loop in R

Hi Cyrene, 

in the exercise we’re tasked with finding the sum of all numbers from i to n. 

Our example shows the solution with i = 1, n = 10. So, we’re looking for the sum of all numbers from 1 to 10, which is 55 = 1 + 2 + …+10

Here is the code:

while(i <= n)
sum <- sum + i
i <- i + 1
print(sum)


Let’s break it down

Line 1 : We compute the sum with a while loop, and the condition i<=n. 

Line 2 : Then we compute the current sum, as :sum = sum + i 

Line 3 : And we increase our current i with 1. 

Line 4 : For convenience we print out the current sum with each iteration

The algorithm terminates when the while condition isn’t through anymore. Hence, when i becomes 11. Leaving us with what we wanted from the beginning: the sum of all numbers from i to n. 

 

Best, 

Eli
