I am trying to solve a bioinformatics problems from a Stepic course.
The problem posed: find clumps of the same pattern within a longer genome.
Motivation: Identifying 3 occurrences of the same pattern within a window of length 500 within a genome allows biologists to find the "replication orig...
Yes, I know the topic has been discussed before. I know that Meta already has threads that complain about how flagging doesn't work. I wanted to give a practical example.

Here's some code that I ran through jsperf to assess its performance. The first test (named EvalLengthBefore++ in the images below) is the way I would consider normally looping through the elements of an array:
var arr = [];
for (var x = 0; x < 1000; x++) {
arr.push(Math.random());
}
var len ...1
BINGO!
Earned all hats in the same row, column, or diagonal.
Hats are arranged in a grid with 5 columns (B-I-N-G-O). Clear a row, column or diagonal and say "BINGO!". Only awarded once per user.
I realize this one stands no chance against Darth Vador, Gandalf, or even a LEGO brick. But loo...
I have tried another program in C++.Excluding the point that the class definition should be in a separate header file,is there anything that needs to be improved?

My experience is that the MVP pattern works better with Windows Forms. It is more or less the same principle.
It also makes it easier to create a WebForms application with the same logic.
Have a look at the following articles:

This is an assignment for class. I would like to know how to improve my code. It is a program to convert Roman numerals to it's decimal equivalent. This is what I have so far. There must be a better way of distinguishing between ex. 'IV' and 'VI' than what I have currently written.

Which one of these two is better?
This one:

return function (req, res, next){

I am trying to write my own vector class, using overloading for certain operations such as input/output of elements and push_back().
How would I overload the addition operator? Right now, I have it cout the individual elements of the array after summing each element of two vectors, but I would l...

In my nested for loops below, it is sometimes necessary to exit the outer loop and then continue program execution. Since loop labels and other goto-like constructions are heavily discouraged, I'm a bit afraid of raptors. Is this usage OK? Is there a better way to structure the program?

This little bit of code is just some code that I wrote from a flowchart at the beginning of a programming and logic book that I have added some to. I tried to create it as an object, I would like a review on what I am doing and if I am doing it right, and what I could do better. I want you to l...
I want to combination the elements in different lists.
For example. Here are 3 lists.
list_a : [ 1,2,3 ]
list_b : [ 4,5,6 ]
list_bb : [ 14,15,16 ]
list_c : [7,8]
list_cc : [17,18]
Because list_b and list_c is mutual exclusive.
Only one of them will exists in the output list.
And list_bb on...
I am constructing a binary tree. Let me know if this is a right way to do it. If not please tell me how to?? I could not find a proper link where constructing a general binary tree has been coded. Everywhere BST is coded.

Given the test code:
import struct
buf = bytearray(b'\xef\xf8\t\xf2')
number = struct.unpack("<I", buf)[0]
How do I cleanly make it work both under Python 2.6 and Python 3.3? The problem is that struct.unpack in Python 2.6 seems to expect a str object (not unicode), so the only way I managed t...
