Please create a solution in CPP to the following problem:
A permutation of size n is an array of size n such that each integer from 1 to n occurs exactly once in this array. An inversion in a permutation p is a pair of indices (i, j) such that i > j and ai < aj. For example, a permutation [4, 1, 3, 2] cont... |

Create a solution in CPP for the following problem:
The weight of a sequence is defined as the number of unordered pairs of indexes (i,j) (here i < j) with same value (a_{i} = a_{j}). For example, the weight of sequence a = [1, 1, 2, 2, 1] is 4. The set of unordered pairs of indexes with same value are (1,... |
