R-4.10 Explain why the plot of the function nc is a straight line with slope c on a log-log scale. C-4.12 Describe a method for finding both the minimum and maximum of n numbers using fewer than 3n/2 comparisons. (Hint: First construct a group of candidate minimums and a group of candidate maximums.) R-4.30 Show that 2n+1 is O(2n) R-4.31 Show that n is O(nlogn). R-4.32 Show that n2 is (nlog n). R-4.33 Show that nlog n is (n
