WebFeb 15, 2024 · Inversion Count for an array indicates – how far (or close) the array is from being sorted. If the array is already sorted, then the inversion count is 0, but if the array is sorted in reverse order, the inversion count is the maximum. Given an array a []. The task is to find the inversion count of a []. WebNov 6, 2016 · A long might be 32 bits, in which case the bit inversion would happen before expansion to 64 bits, and the actual constant used in the test would be 0x00000000FFFF0000. It is easy to construct an input where such test would fail – for instance, for the array of two words: 0xFFFFFFFF and 0x00000001. We can either …
