C++ program for evaluating a polynomial by the brute-force method (not horner)? e.g. 5x3 + 4x2 + 2x + 1

different psuedocode than previous asked question:

And what would the time complexity be?

p 0.0

for i n downto 0 do

power 1 for j 1 to i do //compute xi

power power * x

p p + a[i] * power

return p
