I need to find correct index in a array by comparing ranges. Here is my first try:
int TunerDriver::TunerLookUpTable(double Freq) {
Freq /= 1e6;
if (Freq >= 60 and Freq < 140)
return 1;
else if (Freq >= 180 and Freq < 280)
return 2;

return 3;

I am studying computer science and decided to implement a linked list from scratch for extra practice. To do so, I created a Node class which simply holds an integer, and wrapped the Nodes in a LinkedList class which adds, removes, and returns Nodes. I am wondering how I did, what I can add, and what I can do better.

I have a set of strings that all consist of one or two letters followed by one or two digits. I need to sort by the letters then by the numeric value of the digits.
My solution is quite inefficient in terms of performance; how is it possible to improve it?

This is an implementation of the Damerau-Levenshtein distance in Kotlin which I created as an exercise, but might be also useful, if it proves to be correct.
The implementation is based on this Wikipedia article, even though it does not 100% follow the suggested pseudo-code.

I'm imagining go generate would be a good tool for this. I want to convert strings to ints to save space.

func NewSource(s string) Source {
switch s {
case "Twitter":
return Twitter

return Facebook
case "Gplus":

I'm taking my first steps in the Scala world, though I'm not wholly unfamiliar with functional style.
Apparently one way of calculating Pi is to sum the terms of the infinite series:
$$4 * (\frac{1}{1} - \frac{1}{3} + \frac{1}{5} - \frac{1}{7} + \frac{1}{9} \dots)$$
So I wrote this simple implementation in a Scala work... | stackexchange/codereview |
Problem Statement
I'm reading each line from a .csv file and parsing each comma-delimited value and casting it to the appropriate type:
string[] words = filelines[i].Split(delimiter); // "i" is the 0-based line number
// Remove double quotes encasing the timestamp
DateTime tmStamp = Convert.ToDateTime(words[0].Trim('... | stackexchange/codereview |
I'm trying to extend bootstrap 3 modal window with ability to disable closing it.
I've built this code:
(function ($, window, document, undefined) {
var oldHide = $.fn.modal.Constructor.prototype.hide;
$.fn.modal.Constructor.prototype.hide = function (_relatedTarget) {

I am using this merge sort function to sort table rows by Date, Letter, and Number. It works, but it is super messy and hard for others to read.
The dates are being sorted in two formats YYYY-MM-DD and MM/DD/YYYY which is why there are if statements regulating each format.
And the reason I am differentiating between le... | stackexchange/codereview |
I have the below regex to match email address with atleast one @ and one .
[-0-9a-zA-Z.+_]+@[-0-9a-zA-Z.+_]+\.[a-zA-Z]{2,4}
Am wondering can it be simplified further to match email address with atleast one @ and one .?

I've following code that insert single row in if (rows == 1) { part and inside loop it is batch insert.
So I'm thinking to skip single insert and have it in batch insert code.
