What does function subroutine do?def subroutine( n ): while n > 0: print (n,) n -= 1Question 12Select one:a.Counts from 10 down to 0 and displays each numberb.Counts from n down to 1 and displays each numberc.Calculates the sum of n numbers greater than 0d.Calculates the mean of n
Solution
The function subroutine(n) counts from n down to 1 and displays each number. So, the correct answer is option b.
Here's a step-by-step explanation of how the function works:
- The function
subroutine(n)takes an inputn. - It enters a while loop that continues as long as
nis greater than 0. - Inside the loop, it first prints the current value of
n. - Then, it subtracts 1 from
n. - The loop continues with the new value of
n, repeating steps 3 and 4. - The loop ends when
nis no longer greater than 0, i.e., whennequals 0. - Therefore, the function effectively counts down from
nto 1, printing each number.
