In an array, arr = [a0, a1, …, aN-1] , the elements at indices i and j (where i < j) form an inversion if aI > aJ. In other words, inverted elements and are considered to be “out of order”. To correct an inversion, we can swap adjacent elements.

In number theory and combinatorics, a partition of a positive integer n, also called an integer partition, is a way of writing n as a sum of positive integers. Two sums that differ only in the order of their summands are considered the same partition.
