I have to find the permutation of vector of integers. I need to implement and interleave function vector<vector<int> > interleave(int x , const vector<int> & v); Using interleave we can implement a permute function. vector<vector<int> > permute(size_t n); that returns a vector containing of the first n positive nos. I …

I have the numbers 0-8 so I can represent a state as 012345678 012345687 .... 876543201 876543210 This gives me 40320 ways to represent a state so I have a HashMap of size 40320 and I need a good way to make sure each state only corresponds to 1 key …
