DATA STRUCTURES AND ALGORITHMTopic blast SORTNames Maryum Waris Tahir Khan Isra Jameil Farrukh Ahsan Semester III Section ASubmitted to Sajid Saleem intro shield sort, also known as diminishing increment sort, was devised by Donald Shell in 1959.It is known to be one of the long-standing sorting algorithm.The basic system of logic of this sort is that it virtually divides the original reheel into smaller dip, which consists of elements which are birth at a specified gap, and performs sorting. As the gap decreases original list becomes more and more sorted ,finally when gap is reduced to one, analogy among adjacent elements of list occurs which finally sorts the list.Shell sort utilizes insertion sort. denture SORTWhile sorting a list, insertion sort compares eldest two elements of list (we consider a list with array ground implementation) and sorts them, such that first and second element of list are arranged in required order. Afte r this initial amount, third element is elusive and is sorted according to the two elements previously sorted and so on. curtly comings of insertion sortWhile performing insertion sort if list is arranged in most unsorted manner(worst case) or list of to be sorted is lengthy, the process can be extremely time go through as it involves the comparison and arrangement of every new element considered with different elements already sorted.Improvements with shell sortIf the list is comparatively sorted with excellent disordering, it is easier to sort the list as it will require less swapping upon comparison of elements in the listShell sort improves the sorting process because it compares and non nigh elements which are far apart, and swaps th... ... and 10 while SPACE 13- watch J = SPACE + 1 initialize counter J4-Repeat step 5 ,6 and 9 while J N5-Set K = J - SPACE initialize counter K6-Repeat step 7 and 8 while K 17-If ARRAYK+SPACEa-Interchange ARRAYK+SPACE and ARRAYKend of if structure8-Set K = K-SPACE decrements counter K end of while loop-the-loop in step 69-Set J = J+1 increments counter J end of while loop in step 4 10-Set SPACE = SPACE/2 decrements counter SPACE end of while loop in step 211-Return takes control back to calling function
