(10 points) Assume that all basic operations require the same constant cost C, and by con- centrating on the dominating step(s), compute T(n) for the following program segment: x = 3; y = x; for i = 1 to n do for j = 1 to i do for k = 1 to n do x = x * y - 2 * i * j * k; endfor; for m = 1 to i^2 do y = x + 2 * m; endfor; endfor; endfor
