A Short Note on Computing Permutations

We discuss an algorithm for generating all permutations of numbers between 1 and N. The algorithm is short and efficient, yet its behavior is not obvious from the code, mostly owing to the recursion. The discussion touches upon a few interesting methodological issues and brings in an educational cas...

Abstract We discuss an algorithm for generating all permutations of numbers between 1 and N. The algorithm is short and efficient, yet its behavior is not obvious from the code, mostly owing to the recursion. The discussion touches upon a few interesting methodological issues and brings in an educational case study in recursion.
