Insertion sort on small arrays in merge sort Although merge-sort runs in Θ(n log n) worst-case time and insertion sort runs in Θ(n 2 ) worst-case time, the constant factors in insertion sort can make it faster in practice for small problem sizes on many machines. Thus, it makes sense to coarsen the leaves of the recursion by using insertion sort within merge sort when subproblems become sufficiently small. Consider a modification to merge sort in which n/k sublists of...

Suppose that an algorithm takes 30 seconds for an input of 224 elements (with some particular, but unspecified speed in instructions per second). Estimate how long the same algorithm, running on the same hardware, would take if the input contained 230 elements, and that the algorithm's complexity function is: Big theta not Big O a) Big theta(N) b) Big theta (log N) c) Big theta (N log N) d) Big theta(N^2) Assume that the low-order terms of the complexity functions...

Write a recurrence relation describing the worst case running time of each of the following algorithms, and determine the asymptotic complexity of the function defined by the recurrence relation. Justify your solution by using substitution or a recursion tree. You may NOT use the Master Theorem. Simplify your answers, expressing them in a form such as O(nk) or (nklog n) whenever possible. If the algorithm takes exponential time, then just give an exponential lower bound using the 2 notation. function...
For [Select], there are three choices: worse than, the same as, better than Answer the following questions about the computational properties of divide-and-conquer sorting algorithms, based on tight big-Oh characterizations of the asymptotic growth rate of the functions for the running time or space size, depending on the question. Assume that the input sequence is given as a list, and the output sequence is also a list. Also assume a general implementation of the sorting algorithms, as opposed to an...
