Apply algorithm 4.5.1 in P.173 with n=6 and A=(3,5,4,1,3,2). Draw the corresponding walkthrough as shown in P.173. No subsequent recursive call to Quicksort is needed. Algorithm 4.5.1: QuickSort(p,q)// Assumes an “external" invocation of the form QuickSort(1, n) and// (recursively) sorts A[p], A[p + 1],.., A[q] into order:BeginIf (p < g) ThenM + A[q];j+p;For k + p to (q – 1) DoIf (A[k]< M) Thenx- A[j];A[j] + A[k];A[k] + x;j+j+1;// the if// the for-k loopEnd;End;A[q] + A[j];A[j] + M; // this is the end of the "partitioning"QuickSort( p,j- 1);QuickSort(j+1, q ); |/ the second "recursive" sub-call// the first "recursive" sub-call// the if-statement at the beginning// the recursive algorithmEnd;End.Walkthrough assuming an "external" invocation of the form Q(1, 11); that is,// QuickSort the array A from position, p = 1 to the last position, q = 11.A1= pq = 11kA[k] A[k]<=3// and first j= 4Now, p = 1 and j – 1 = 3, so the next "action" taken by QuickSort is theinvocation of QuickSort itself with new parameter values, QuickSort(1,3).Before continuing the walk through, we digress for a moment to describe acommon mechanism for implementing recursion (in modern high-level computerlanguages).

Implement MSD string sorting using queues, as follows: Keep onequeue for each bin. On a first pass through the items to be sorted, insert each item intothe appropriate queue, according to its leading character value. Then, sort the sublistsand stitch together all the queues to make a sorted whole. Note that this method doesnot involve keeping the count[] arrays within the recursive method.
IN PYTHON, USING RECURSION: ask the user for the length of a square and the character they want to use. Draw the square. Once the user creates the square with their specification, ask them if they want it to be smaller or larger and how many times. Draw all the squares growing in size to the specified range. (the last solution someone gave me here did not work. Also please tryh to use a recursive queue.)

Consider the following variation on MergeSort: instead of dividing a list (say, of integers) evenly (that is, half and half or half and half plus 1) at all levels of recursion, we choose to divide a list this way - a left list that consists of exactly one integer and a right list that consists of the remaining integers. The time-complexity of this variation of MergeSort is: (a) O(n log n) (b) O(n²) (c) O(n) (d) none of the above
