The amortized complexity of std::next_permutation?

http://stackoverflow.com/questions/4973077/the-amortized-complexity-of-stdnext-permutation

be errors in the below Let us count the total number of swaps done. We get the recurrence relation T n 1 n 1 T n &Theta n.. n 1 T n comes from fixing the first element and doing the swaps for the remaining n. &Theta n 2 comes from changing the first.. At the point we change the first element we do &Theta n swaps. Do that n times you get &Theta n 2 . Now let X n T n n Then..
