I implemented a Karatsuba algorithm in Python but it doesn't give me the exact answer.
def karatsuba(x, y):
if x < 10 or y < 10:
return x*y
#making the two numbers strings here
str_x = str(x)
str_y = str(y)
#finding the mid point for each number here
n = max(le...
As per WIKI An anagram is direct word switch or word play, the result of rearranging the letters of a word or phrase to produce a new word or phrase, using all the original letters exactly once; for example, the word anagram can be rearranged into "nag a ram".
I am trying to reproduce results from a research paper using python. I've checked my method and it works on relatively small sample datasets. However, the code does not run for my actual dataset, which is initially ~11,000 data points and becomes ~40,000 data points after padding zeroes. The algo...
I am writing a bunch of Math related classes:BigInteger,Fraction,matrix,vector,polynomial,set etc.All of these classes will use each other.The classes will either work in decimal format or in Rational format at a time(eg as FractionalMatrix and DecimalMatrix) so I thought it will be best to imple...
i have a two dimensional array lets say int[][] arr=new int[9][9] ,or a 2/3 array.
The question is i want to check each row of the array for knowing ,does it have any repeated elements in that row?
having a hard time to achieve what I'm looking for. I was thinking of using arrays but don't know where to start. Code below is what I want to shorten to get rid of multiple if statement using jQuery.

Say I have a plot as shown in the figure for which I want to find the following
$$I = \int_0^\infty C(t) dt$$
This graph can be fitted with multi-exponential functions.
I know that the idea would be to integrate that fitted function to infinity instead. (I am sure there are smarter ways too!...

I've created a Mixin in Less CSS. It can do the following things:
Set the position-rule of an element.
Place the element in one of the corners (e.g. top left, bottom right etc.)
Alternatively it can set explicit values for top|right|bottom|left.
Usage example:
.test-1 {
.position(absolut...
I've created a scraper using vba which is able to parse json response. When I was thinking of using scripting dictionary or json converter to scrape json data I could notice that applying split function on responsetext is fairly easy to get the expected outcome. It is working great now. I've writ...
I'm currently developing a XML converter for a model of my app in PHP. Therefore I'm using a Pipeline Pattern, which passes a "payload-document" through each pipe and appends different information of the model to it. This works well.
My Problem

A FASM Program that prompts a user to enter 2 values,x and y divides them then displays a quotient and a reminder.I am so much a beginner in assembly programming and have no idea on where to begin .kindly include comments in the program.
I have this task where I have an associated array in PHP and I want to manipulate the order of entries. Basically I want to be able to move entry Y before entry X.
So basically if I have the following array:
['foo1' => 'bar', 'foo2' => 'buzz', 'foo3' => 'bazz']
I want to be able to say: 'put ...

I am wondering if using a std::map or std::list could lead to false sharing issues in a multithreaded environment, if one is processing things like integers which won't fill an entire cache line.
As far as I know, this could only become a problem with variables which are smaller than a 64 bit in...
