please solve a b c d and find total flop count and algorithm flop count and show if each one of a b c d is linear, quadratic or cubic

Whenever a problem asks for the development of an algorithm, do a flop count. 9.1 What is the flop count for each code segment? a. sum =0.0; for i=1:n sum = sum +n2; b. x=0.0:.01:2pi; n=1 ength(x); sum =0.0; for i=1: length sum = sum +1/(x(i)2+x(i)+1); end c. A=rand(5,8); B=rand(8,6); C=rand(6,12); D=ABC d. x=rand(10,1); y=rand((10,1); z=xy
