## What is Inverse Function

The number of inversions (disorder) in a permutation is the number of pairs of elements (not necessarily adjacent) in which the next element has a lower number than the previous one. The number of inversions (disorder) in a permutation is the number of pairs of elements (not necessarily adjacent) in which the next element has a lower number than the previous one.

Each sequence of k different elements, taking into account the order, is called a permutation of these elements. Consequently, permutations of k elements differ from each other only in the order of their elements. This online calculator allows you to find the number of permutations of n elements.

By definition, an inversion is formed by two numbers in a permutation when the smaller of them is located to the right of the larger one. Each permutation can be associated with the number of inversions in it, which is calculated as follows: for each of the numbers, the number of smaller numbers standing to the right is determined, and the results obtained are added.

The modern way of life requires constant dynamics. Making calculations on a calculator, we significantly save our time, do not risk making mistakes and get an accurate result. Thanks to the invention of this device, many people have forgotten what shortages and errors in calculations are. However, there is a difference between a calculator and a calculator, and if primitive computational functions can be done on a mathematical model, then the most complex calculations can only be done with the help of engineering. From now on, you do not need to purchase this miracle of modern technology - just turn to our online engineering calculator for help! The program works without additional installation - just go to the website and start acting.
