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...

Consider a variation of Merge sort called 4-way Merge sort. Instead of splitting the array into two parts like Merge sort, 4-way Merge sort splits the array into four parts. 4-way Merge divides the input array into fourths, calls itself for each fourth and then merges the four sorted fourths. a) Give pseudocode for 4-way Merge sort. b) State a recurrence for the number of comparisons executed by 4-way Merge sort and solve to determine the asymptotic running time.

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...

For each of the following problems write a recurrence relation
describing the running time of each of the following algorithms and
determine the asymptotic complexity of the function defined by the
recurrence relation. Justify your solution using substitution and
carefully computing lower and upper bounds for the sums. Simplify
and express your answer as Θ(n k ) or Θ(n k (log n)) wherever
possible. If the algorithm takes exponential time, then just give
exponential lower bounds.
