For the problem given:
Douglas Hofstadter’s Pulitzer-prize-winning book, Gödel, Escher, Bach, poses the following mathematical puzzle.
Pick a positive integer n as the start.
If n is even, divide it by 2.
If n is odd, multipy it by 3 and add 1.
Continue this process until n is 1.
...
Why do you have to use recursion?
What's wrong with
while n > 1:
if n % 2 == 0:
n = n / 2
else:
n = ((n * 3) + 1)
print(n)
?
Recursion just complicates the program. You can freely add count to the function like this too.
I am creating a shopping cart application to learn Spring MVC. I want to display list of all categories and subcategories in more than one page. i.e; Home Page, Products page, Category page.
In the Home Page controller I am retrieving the list of categories,subcategories and featured products an...
Hi I've got a problem where I need to parse a line in a parameter file of the form

I've got code which works however it seems like it will be horrendous to maintain when I add more than a few options here.

Any ways I would be able to clean this code up to become more user friendly and/or add additional functions to increase user-friendliness. Also if possible, could you tell me a way to sort the text function by numerical value and A-Z

Naming
The Java naming convention for arguments is camelCase. You should rename :
public int solution(int[] A)
For something that could look like the following code, or use a better name that would fit your need :
public int solution(int[] arrayA)
I don't have anything against a varia...
FizzBuzz was fun, and I got great feedback and learned a few things (which I hope I put in practice here), but only scratched the surface. I wanted to explore the LOLCODE language a bit more, so I implemented a little rock-paper-scissors, to play with functions, parameters, return values.. and us...
If we list all the natural numbers below 10 that are multiples of 3 or
5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the multiples of 3 or 5 below 1000.
My solution:
#include <stdio.h>
#define TOP_LIMIT 1000
float sum_of_series(float start_from,float...

Well, this is an answer to a Project Euler question after all, so perhaps the best solution is basically a pencil-paper one.
sum(i for i in range(n + 1)) # sums all numbers from zero to n
is a triangular number, the same as
n * (n + 1) / 2
This is the triangular function we all know and lov...
So I have sparrows, which are sentient and intelligent, which are physically exactly still just the same, no extra hands or anything, so any weapon would have to be held in the feet or somehow attached to the wings.
They have roughly the mentality of this .gif, and I would imagine that simply ho...
The problem: I have a list with n items and i need a loop n that loops n times.
Here is my solution:
# myList = ...
for n in range(len(myList)):
# do stuff
enumerate:
# myList2 = ...
for n, _ in enumerate(myList2):
# do stuff
Are there any other ways to do this in a pythonic way, e...
Haven't any experience writing recursive functions.(Generally tend to avoid them - not sure if that's a negative). What do you think about the following?
This is also my first time using JUnit, I'd appreciate input if I'm doing something wrong there.

I'm trying to figure out a good way to represent information for a custom ribbon and would like feedback. Here is what I have so far:

is button undoable?
