Exercise 3.3.4: Impact of quantum size. info About n processes are time-sharing the CPU. The average total CPU time is T. The time quantum is Q. The context switching overhead is S. Determine the fraction of CPU time wasted on context switching for the following cases: (a) T < Q (b) T >> Q (c) Q approaches 0 (d) Under what condition will the wasted fraction of CPU time be 50%

Function name: poly parameters: int returns: int description: a polynomial of degree n with coefficients a0,a1,a2,a3, . . ,an is the function p(x) = a0+a1x+a2x2+a3 ∗ x3+ . . +an ∗ xn this function can be evaluated at different values of x. for example, if: p(x) = 1+2x+ x2, then p(2) = 1+2 ∗ 2+22 = 9. if p(x) = 1+x2+x4, then p(2) = 21 and p(3) = 91. write a function poly() that takes as input a list of coefficients a0, a1, a2, a3, . . , an of a polynomial p(x) and a value x. the function will return poly(x), which is the value of the polynomial when evaluated at x.
