WebPair of positions in a sequence where two elements are out of sorted order Permutation with one of its inversions highlighted. An inversion may be denoted by the pair of places (2, 4) or the pair of elements (5, 2). The inversions of this permutation using element-based notation are: (3, 1), (3, 2), (5, 1), (5, 2), and (5,4).

WebFor the first part, observe that the number of inversions cannot exceed the number of ways to choose two numbers (since each pair accounts for at most one inversion). Hence, the number of inversions cannot exceed ( n 2) = n ( n − 1) 2. As for the second part, how else would you make a permutation with a lot of inversions? bupa dentist newcastle
