I need help to solve this task using while statement

[Pranav]

Try using the following steps.

Within the function declare a variable k and check the condition within the while loop.

  k=1
  while(k<(n-1)): 
      .....step1
      .....step2
      k+=1

STEP1:Using modulo operator check if the variable k is a multiple of n.
STEP2:Increment the value of k every time to another variable(sum) if the above condition is True.
