code challenge fun

	package main

	import "log"

	func main() {
	numbers := []int{23, 2, 4, 7, 2, 11}
	find := 20 // should return true
	// numbers := []int{1, 3, 5, 23, 2}

davidvthecoder / round.go

Created April 9, 2014 19:58

Arggh Golang does not include a round function in the standard math package. So I wrote a quick one.

	package main

	import (
	"log"
	"math"
	)

	func Round(val float64, roundOn float64, places int ) (newVal float64) {
	var round float64
	pow := math.Pow(10, float64(places))

davidvthecoder / CSVwriterExample

Created October 9, 2013 18:32

Golang CSV Writer Example for a Web Application - Warning No error handling, just the basic concept.

	import (
	"../../web"
	"bytes"
	"encoding/csv"
	}

	func GenerateCSV(ctx *web.Context, args ...string) {

	record := []string{"test1", "test2", "test3"} // just some test data to use for the wr.Writer() method below.

davidvthecoder / FindRanges.cs

Created September 9, 2013 19:28

Handy Non-recursive way to find the contiguous natural number ranges given a list of numbers. For example: A list of numbers 1,2,3,6,7,8,9,14,15,22 the contiguous ranges would be: 1-3, 6-9, 14-15, 22-22 Potential issues: since it finds all the missing Numbers, ranges with huge gaps of missing numbers can hinder performance.

	public List<Range> findRanges(List<int> numbers) {
	List<Range> ranges = new List<Range>(); // create a list of ranges that will eventually be populated.
	numbers = numbers.OrderBy(x=>x).ToList<int>(); // order the list of numbers coming in.
	int min = numbers.Min(); // get the smallest number
	int max = numbers.Max(); // get the largest number
	List<int> missingNumbers = new List<int>(); // create an empty list of missing numbers
	int i = min; // create a counter for stepping through all the numbers starting with the smallest number
	while (i < max) { // step through each possible number from min to max.
	if (!numbers.Contains(i)) { // if the number doesnt exist from our list, its a missing number
	// found a gap in the number (missing number)
