The sorting algorithm used in this method is Dual-Pivot Quicksort. In other words ... The problem is that if passing 'c' and 'b' makes the comparison return a negative value, then passing 'b' and 'c' should return a positive one (And your first version returns a negative number in that case instead). If the function doesn't return consistent results no matter the order of arguments, the sort algorithm is going to produce a …In step 1, we should store the indexes instead of elements. Input: arr [] = {2 5 2 8 5 6 8 8} Step1: Sort the array, After sorting we get: 2 2 5 5 6 8 8 8. indexes: 0 2 1 4 5 3 6 7. Step 2: Now construct the 2D array to maintain the count of every element as. Index, Count. 0, 2. 1, 2.
