G64ADS Advanced Data Structures

G64ADS Advanced Data Structures. Sorting. Insertion sort. 1) Initially p = 1 2) Let the first p elements be sorted. 3) Insert the (p+1)th element properly in the list so that now p+1 elements are sorted. 4) increment p and go to step (3). Insertion sort. 3. Insertion sort.
