you're going to hate me for asking such a simple question but I don't understand why this code won't work!
test = input('Please enter an integer:')
vec = []'
B = int2str(test)
for i = 1:length(test)
vec = [vec;B(i)]
end
C = kron(vec,ones(100,1))
So basically what it's supposed to do is...
Using the table data gateway (TDG) pattern, I created a class QuestionGateway for retrieving, adding, updating, deleting, and sorting multiple-choice questions.

}

Take my implementation:

m = len(sequence) / 2

def merge(left, right):
result = []
i = j = 0
while i < len(left) and j < len(right):

Of course the when this select is comes with less options it will be better to leave it like this, and when it comes more then this it better to make it via loop.
The question is that if I should make it loop or leave it as it is ?
which way is the best and why ?

Answers sometimes become obsolete. New solutions arise that were not technically feasible at the time that the question was originally posed. People decide that the old way of doing things is no longer a good idea. This goes for answers on main sites as well as on meta sites.

I wrote (several months ago) a program that will take an input file, with a provided std::string, and append that to each individual line in the file. Looking at the code again, I am wondering about the performance of this program, possibly if the file is very large or any of the lines/input stri...
I need a function I can put on a form which does:
Calculates number of working days until a given date
Excludes weekends

with

As it currently stands the code works fine. Is there a way to optimize the code in the class Neighbours.

I'm building a site which consists of 5 full-height columns floated in a line. The first column on the left is the header which does not move. The four columns to the right of the header, once clicked, the clicked column moves to the far left next to the header, and the other columns collapse, ...
I have made an AVL Tree. It works and does what it needs to do. I only need it to insert and search. I am comparing how long it takes to load and search a dictionary file in relation to other various data structures. My AVL Tree takes 25 seconds to load the file.

The fact is there is a hardware delay that you can't ignore. Try to pass a float to your interval. Kill zombies after each update may help too.

You are organizing your algorithms into two categories: working algorithms and non-working algorithms; this is rather Manichean. You should try to design something where an algorithm is not "working" but "approaching the expected result better than the other ones". In other words, don't try to fi...
