1. Please answer these

1. Consider the following integers in an unsorted array A = [3,7,9,0,5,1,6, 8,4,2, 0,6, 1,5, 7,3,4,9,8,2). Assume that you use the sequence {1,3,7,15} to perform Shell sort. In particular, we refer to an iteration of sorting k sub-arrays as k-sorting. Show the contents of A after (i) 15-sorting. (ii) 7-sorting, and (iii) 3-sorting. Of course, we assume that we perform 15-sorting. 7-sorting, and 3-sorting consecutively. 2. Consider the following procedure that generates a sequence of integers that could be used for Shell sorting n > 0 elements. The integers in the sequence used for Shell sorting are assigned to the variable k. Generate Sequence (n) 01. k+ 1; 02. P + 1; 03. while (k <>
