   # Function Invoking
   def sumN(n):
       sum = 0
       for i in range(n+1):
           sum = sum + i
       print(sum)
   
   def sumNCube(n):
       sum = 0
       for i in range(n+1):
           sum = sum + i**3
       print(sum)
   
   def main():
       print( sumN(5), sumNCube(5) )
   
   main()
   
   
   
   
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).

       print(aList)
       append(aList, 4)
       print(aList)
   
   def append(s, n):
