Before I start, I have to apologize for bringing up another case of permutations with duplicates. I have gone through most of the search results and can’t really find what I am looking for. I have read about the Lexicographical order and have implemented it. For this question, I am suppose to implement a recursion method that prints out the

Java recursive Fibonacci sequence
Please explain this simple code: I’m confused with the last line especially because if n = 5 for example, then fibonacci(4) + fibonacci(3) would be called and so on but I don’t understand how this algorithm calculates the value at index 5 by this method. Please explain with a lot of detail! Answer In fibonacci sequence each item is the
StackOverflowError when running my “Knight’s Tour” (it’s pretty much finished otherwise)
I’m trying to make a program that goes through all squares of a chessboard (size doesn’t really matter, but for now it’s 6×6) with a knight, called a “Knight’s Tour” check it out on wiki. The tour is supposed to be closed, which means the knight on the last visited square can “attack” the square he started at. The code
Create a triangle out of stars using only recursion
I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: This code works with the iterative but I can’t adapt it to be recursive. I should note that you cannot use any class level variables or any
Is there any way to do n-level nested loops in Java?
In other words, can I do something like Except N times? In other words, when the method creating the loops is called, it is given some parameter N, and the method would then create N of these loops nested one in another? Of course, the idea is that there should be an “easy” or “the usual” way of doing it.
