If u r using (n*n*(n+1)*(n+1))/4 formula then use long long data type . It works for me and I got AC.

I donot understand how to calculate the minimum exchange opereation.
Can someone expline?

Hi
There is function called next_permutation() at the STL library algorithm.h
You can use that. It is just a two line program.
