   # Function Definition & Invocation
   def sumN(N):
       a = 0
       for i in range(N):
           a = a + (i+1)
       return a
   
   def sumNCube(N):
       a = 0
       for i in range(N):
           a = a + ((i+1)**3)
       return a
   
   print(sumN(5), sumNCube(5))
   
   
2. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   # Function Parameters and Return Values

       for i in range(n):
           print('*', end='')
       print()
       return n
   
   print( stars(3) + stars(5) )
   
   
3. (10%) Determine whether the following code is correct or not.  If it is correct, predict its output.  If it is incorrect, point out the mistake(s).
   
   # Pass by Value

       a = b
       a = c
       print("The maximum value is", a)
       return a
