Until the day when an LTS release optimizes for this programming construct, it is best to view these Java recursion examples as educational tools. Stick with iterative constructs in the systems you ...

def perms(s, temp): """s is a string, temp is part of the output found so far.""" if len(s) == 0: print temp return for i in s: s2 = s.replace(i, '') temp += i perms ...

Good programmers need to create code that efficiently solves problems ... which will add to the complexity of the program. This Java palindrome example uses recursion, which is an advanced concept.
