I have read about the Lexicographical order and have implemented it. For this question, I am suppose to implement …

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…
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 squ…
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 clas…
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 usualR…
