Assuming that all basic operations require the same constant cost C, by concentrating on the dominating step(s), compute the cost of the resource function R(n) for the following program segment in closed-form. x = 2; y = 10; for i = 1 to n do for j = i to n do y= x *y/2; for k = 1 toj do x=x+y-10; endfor; endfor; endfor;
