Inverse Permutation Question in c++ 2011-12
Inverse permutations from an array of permutations. It's my first time coding on permutations so I don't have any experience on this. So I came up with a solution to just swap the array and the element number as the inverted permutation

v

Code:

oid inverse ( unsigned ip[], const unsigned p[], unsigned elements ) { unsigned tempArray = 0, tempIndex = 0; for (int i = 0; i < elements; i++ ) { tempIndex = i; tempArray = p[i]; ip[tempArray] = tempIndex; } show ( ip, 5 ); }
