WebThe functioning of the 3 way quick sort is similar to that of the conventional quick sort. Here, a pivot element is selected, and elements are rearranged and three partitions are formed as follows: Elements which are less than the pivot element. Elements equal to the pivot element. Elements greater than the pivot element. WebAnswer: Yes - it is the same technique in both DNF and 3-day quick sort but just that the technique is applied recursively in 3-way quick sort till everything is sorted (the interval becomes single element - bottoms out condition) By the way, both of these DNF and 3-way partitioning algorithms a...
