(25 pts) For each of the following code fragments: (a) Compute the worst-case run time as a function of n, i.e give the cxact expression for T(n). If there are any summations, simplify them. Show your work (i.e. next to each primitive statement write the total number of times it gets executed. You may assume that primitive statements have cost 1. Do not give just the final answers (b) Circle the higest order term and drop any multiplicative constants. What is the worst- case asymptotic time complerity T(n) of the algorithm
