The sum of squares of n is n2 + (n-1)2 + (n-2)2 + + 12 for n> =1.write code that uses a for loop (not a while or do loop) that starts the loop counter i at n, and reduces i by 1, as long as i is > = 1, and inside the loop we accumulate i2. after the loop is done, return the accumulated value. now place this code inside a function named squaresof, which takes one parameter n as integer, and returns an integer. declare all other needed variables. note that you must write the function definition and name and use the variables (and their names) above exactly as noted. you may add other variables as needed. do not add any other code here.
