Hello,
I am not able to understand the solution for the problem: Permutations of a String
The text explanation is very weak for the recursive case as to why two times swapping is done and also in the visual slide very short example is explained through which it is not clear.
Please provide a simple explanation for the same as to how the recursion stack works for a big example and most important what is the intuition behind using two swap and recursive call in between swaps.
