Given a variable $n$ refers to a positive int value, use two additional variables, $k$ and total to write a for loop to compute the sum of the cubes of the first $n$

counting numbers, and store this value in total. Thus your code should put $1**1**1+2**2**2+3**3**3+$dots$+n**n**n$ into total. Use no variables other than $n,$ k$,$

and total.
